Here’s some solid and down-to-earth advice from the engineering team over at 7Block Labs.

P A I N -- A G I T A T I O N -- S O L U T I O N

P A I N

We've all had those days, right? You know, when stress and frustration just seem to stack up out of nowhere. Life can really throw us some curveballs, whether it’s work, relationships, or just the everyday stuff. Sometimes it feels like we’re juggling a million things at once! Hey, you're definitely not the only one who feels overwhelmed or like you're just treading water.

A G I T A T I O N

When stress starts to pile up, it can really get under your skin and make you feel on edge. You might catch yourself getting a bit cranky with your loved ones, having a tough time concentrating, or just feeling a little more anxious than usual. Feeling irritated all the time can really take a toll on both your mind and body. It can make it tough to handle everyday challenges that come your way.

Common Triggers

Work deadlines: It can sometimes feel like the pressure just doesn't let up.
Relationship troubles: Dealing with conflicts can really wear you out. It zaps your energy and tests your patience.
Financial worries: Dealing with money issues can really weigh you down.
Health issues: When you're dealing with physical pain, it can really mess with your head.

S O L U T I O N

Feeling overwhelmed or in pain can be tough, right? If you're looking for some ways to ease that discomfort and chill out a bit, I've got a few strategies that could really help you out. Here’s what you might want to try:

1. Take a Breather

Sometimes, you just need to hit the pause button for a moment. Why not step outside for a bit? Take some deep breaths, or if you prefer, just sit quietly for a few moments. It can really help clear your mind. This could really help you clear your head.

2. Talk it Out

Having a good chat with a friend or someone you care about can really be amazing. Talking about your feelings can really help lift some of that weight off your shoulders and might even help you see things in a new light.

3. Get Moving

Exercising is a fantastic way to release all that pent-up energy and frustration. Just a quick stroll can really lift your spirits and help you feel more grounded.

4. Try Mindfulness

You know, things like meditation and yoga can be super beneficial. They really push you to stay in the moment and handle stress better.

5. Seek Professional Help

If you’ve been feeling stuck for a bit, don’t think twice about talking to a mental health pro. They can really help! Hey, we all hit those moments when we could really use a little extra help, right?

Just keep in mind, it’s really about figuring out what clicks for you. Life can throw some serious curveballs at us, but there are definitely ways to get through the chaos. You got this!.

1) Pain: the specific integration headaches you’re wrestling with

Security hiccups: It looks like your proof of concept is off to a good start, but it’s hitting a few bumps along the way. Specifically, it’s struggling with SOC 2 evidence, KMS-backed signing, VPC isolation for RPC, sanctions screening, and integrating SIEM hooks.
So, AWS KMS now supports secp256k1 and Ed25519, which is pretty cool! But when it comes to your signing flow, there are some differences you’ll want to keep in mind--especially when it comes to ASN. The 1 and P1363 formats aren’t quite there yet, and honestly, your audit trails aren’t ready for prime time either. Check out more here.
Data plumbing debt: Finance needs real-time data with sub-second response times and on-chain proofs, but it looks like your indexers are just idly polling one after the other through RPC. Hey, you’re really missing out on this awesome streaming pipeline that’s super flexible and can run in parallel--kind of like Substreams or Subsquid. It’s designed to easily connect to Kafka or any SIEM, and it even has replay capabilities. It could really level up your data handling! Get the details here.
Cross-chain risk: So, your procurement team is aiming for a single standard to make everything work together seamlessly. But honestly, it feels like the bridges are just a chaotic mess right now! Hey, guess what? The OP Stack fault proofs have officially pushed Optimism chains into Stage 1! This means they now have permissionless withdrawals and challengeable proposals. Pretty exciting stuff! On the other hand, Polygon is busy launching its AggLayer with a Unified Bridge that’s using pessimistic proofs. Lots of cool developments happening in the blockchain space right now! It seems like your risk model is a bit behind on the latest stuff. If you want to dive deeper into this topic, just click on this link here. It’s got all the details you need!
Legacy system fit: So, here's the deal. The teams in Treasury, Fund Ops, and Corporate Actions are all buzzing about ISO 20022 and Swift, but when it comes to your Web3 stack? Not really in the conversation. Hey! So, there are some pretty exciting pilots happening with Chainlink and Swift/DTCC that demonstrate how to route tokenized fund workflows using the systems we already have. However, it seems like your current setup isn't quite ready to handle that just yet. If you want to dive deeper into that topic, you can check out more details here. It’s got some interesting insights!
Changing landscape of L2 economics: Ever since Ethereum’s Dencun upgrade (that’s EIP-4844 for the techies out there), we’ve seen a huge drop in L2 fees--down by as much as 94-99%. It’s pretty impressive how rolling up data into those temporary blobs has made such a difference! I get what you're saying, but your total cost of ownership model still relies on those outdated calldata costs. Curious to learn more? You can check it out here. Enjoy!

2) Agitation: The Business Risk If You Don’t Fix It Now

Missed deadlines lead to budget overruns: Honestly, we all know that big IT projects can turn into a bit of a black hole for money. It's not uncommon for them to exceed the budget by around 45% and fall behind schedule by about 7%. It’s a frustrating reality! The longer you put it off, the more those risks start piling up. Every time we put off a decision about Dencun, we're just racking up unnecessary platform costs for another quarter. (mckinsey.com).
Compliance issues = Missed opportunities: The updated SOC 2 requirements from 2022 really emphasize the need for strong controls in areas like risk assessment, change management, logging, and privacy. If companies don't get these right, they risk losing out on deals! On top of that, ISO 27001:2022 has shaken things up a bit with the way they group controls and added 11 brand new ones. Some of these include areas like Threat Intelligence and Data Loss Prevention (DLP). It's definitely a fresh take! If you're not in compliance, you could end up delaying those go-live dates even more. (aicpa-cima.com).

Hey everyone! Just a quick heads up--DORA is shaking things up a bit by adding a new metric in 2024: the Deployment Rework Rate. This could mean more stable releases for us, so it’s definitely something to keep an eye on! When teams overlook stability metrics, they often find themselves struggling with throughput during user acceptance testing and the hypercare phase. Make sure to keep everything running smoothly to steer clear of any chaos! You can check out more about it here.

Vendor lock-in → Reliability issues: When you depend too heavily on just one vendor, it can really backfire and cause some serious reliability problems. To tackle this issue, using PrivateLink along with multi-provider failover and DIN-style diversity can really cut down your risk. (status.privy.io).

3) Solution: 7Block’s Integration Blueprint (90-day pilot to production scale)

We put together cohesive and compliant solutions that really simplify things for your security, finance, and engineering teams--without drowning in unnecessary complexity. Take a look at the key elements I've put together for you below. We've also thrown in some links to related services wherever it fits, just to give you a better idea of what we have on offer.

A. Network and Key Management Hardening

Private RPC Ingress: We’ve got you covered with all your chain connectivity needs right in your VPC, thanks to AWS PrivateLink. And guess what? It's even got cross-region functionality now! So, this gives us access to a multi-provider RPC pool. It’s got a mix of enterprise nodes along with different providers, which is pretty cool. We've set up health and liveness checks, circuit breakers, and a weighted failover system to keep everything running smoothly. So, what does that mean for you? Well, you’ll have private IPs, no public egress, and some solid, straightforward audit logs for SOX compliance. It's all about keeping things secure and organized! Check it out here.
Signing Policy with AWS KMS: When it comes to signing, we suggest going with ECC_SECG_P256K1 for ECDSA on EVM. For other situations where it fits better, Ed25519 is a solid choice too! We also take care of normalizing KMS's ASN. We’re looking at adding one signature to P1363 to make it easier for the downstream toolchain integration. Also, we make sure to implement kms:SigningAlgorithm and set up per-key IAM policies that fit neatly with your RACI. If you're looking for a little more security, you might want to check out Nitro Enclaves or HSM-backed cosigners. They can really add an extra layer of protection! More details here.
Double Layer of Sanctions Controls: We're all about keeping you safe! First up, we’ve got pre-trade checks in place using the Chainalysis Screening API right on the server-side. Plus, we’re adding another layer of protection with on-chain guardrails through the Chainalysis sanctions oracle in important Solidity transactions. You can trade with confidence! So, with this approach, everything connects back to the SOC 2 CC series controls. Want to dive deeper? Check it out here. You’ll find all the details you need!
How 7Block Can Help: We’re all about helping you with VPC design, managing RPC ingress, handling custody and signing flows, and even navigating sanctions gating. Check out our blockchain integration services to see what we can do for you!

B. Smart Contract Baseline: Secure, Maintainable, and Gas-Aware

Solidity Toolchain Cadence: Let’s target version 0.

8. Make sure you're at version 31 or higher to keep up with the upcoming deprecations linked to 0. It’s a good idea to stay ahead of the game! 9. 0. Don't forget to add support for the new opcodes and the layout specifiers for storage. It's super important! Oh, and definitely avoid the old version! transferand. It's time to move on from the old send methods and start using custom errors instead. If you’re curious and want to dive deeper, check out the details on the Solidity blog. It's got all the info you need!

Library Options: I’d recommend checking out OpenZeppelin Contracts v5. It’s a solid choice! 1 or v5.

2. To streamline your setup and save on gas and storage fees, make sure to take advantage of tools like ReentrancyGuardTransient for temporary storage. Also, don’t forget about the Packing utilities and the Account Abstraction modules (like ERC-4337 and ERC-7579). These can really help you define permissions more effectively! Hey, if you're looking for more info, you might want to check this out: OpenZeppelin. It's got some pretty cool stuff!

Check Out These Patterns: Seriously, it’s smart to look into role-based access control (RBAC) for better security. You might want to set up some pull-payment vaults too. And hey, think about adding some pausability with timelocks just to be on the safe side! Also, bringing together on-chain allow/deny lists with sanctions oracles can really help you stay compliant with regulations in your operations.
What 7Block is All About: At 7Block, we really focus on the whole process of design and implementation, especially when it comes to smart contract development. Check out more about what we do here! On top of that, we provide in-depth reviews with our security audit services and all-encompassing web3 development services. We've got you covered!

C. Data Plane: Reliable Streaming Indexers You Can Trust!

Parallel Indexing: Finally, no more waiting around for slow serial RPC polling! Thanks to The Graph’s Firehose and Substreams (or Subsquid), we can effortlessly stream normalized events straight into Kafka/Postgres in no time. We stream operational signals directly to Splunk or Datadog, and in return, you get valuable business insights--think positions, PnL, and NAV--all backed up with the cool added feature of blockchain verifiability. On top of that, Substreams is really a game changer. It cuts down sync times from days to just a few hours, and it even allows for almost real-time streaming. How cool is that? If you're curious about the specifics, you can find all the details right here. Give it a look!
Observability: So, when it comes to OpenTelemetry, it really has you covered from top to bottom. We're talking about everything from the sequencer and gateway all the way to the indexer and sinks. It's like a full toolkit for monitoring your system! With Splunk dashboards and alerts, you can easily keep an eye on DORA’s five key metrics. Leaders are really seeing some great returns on their observability practices, which is awesome news for making your business case. If you're curious and want to dive deeper into the topic, feel free to check it out here. You'll find some really interesting insights!

D. Cross-chain without the bridge roulette

OP Stack fault proofs: So, we've got Stage 1 permissionless proofs up and running on OP Mainnet now! It’s exciting because it really shows that we’re moving in the direction of OP-based Layer 2s. Hey, just a little heads up--don’t forget about the governance fallback! It’s definitely worth keeping in mind. This change definitely shakes things up with how you trust your system, so it's a good idea to update your withdrawal SLAs and incident runbooks to reflect that. If you want to dive deeper into the details, just click here for more info!
Polygon AggLayer: Hey there! If your blockchain is getting on board with the AggLayer hype, you’re really in for something special! The Unified Bridge combined with those pessimistic proofs is all about enhancing the safety of transactions between Layer 2s. It's a game changer! Plus, you can check out the AggSandbox to easily validate message timing and proofs between L2s locally. It's a handy tool for doing just that! Check out the announcement right here!
Chainlink CCIP for institutions: If you're looking for reliable, bank-level interoperability and need to stay aligned with ISO 20022 (think along the lines of Swift or DTCC), the CCIP has got you covered! It offers a straightforward, standardized way to connect your current systems to on-chain settlement and messaging. It's pretty handy! If you're looking for more details, you can check it out here.
What 7Block is all about: We're here to help with choosing and putting into action the right protocols. Our focus is on developing cool cross-chain solutions and building blockchain bridges that really connect everything together. If you're curious, check out what we do in more detail here and here.

E. Zero-Knowledge: Adding Business Value (Not Just Resume-Driven Crypto)

Proof Systems: If you’re interested in verifying computations or want to keep things private, we really dive into zkVMs, particularly the Succinct SP1 Hypercube. It's pretty fascinating stuff! They’ve managed to nail down Ethereum block proofs in less than 12 seconds, which is pretty impressive! Plus, they keep the on-chain verification costs nice and low, hanging around 275k gas.
We'll only bring them in when they actually help us speed things up with settlements or reduce those pesky counterparty risks. (Read more here).
Governance-Friendly ZK: In the world of compliance enclaves--think credit scores or portfolio proofs--we're all about keeping vendor lock-in to a minimum. We're all about making everything easy to track and understand. That's why we focus on being transparent with open constraints and sharing our audit results with everyone. (Check it out).
7Block’s Role: We weave ZK architecture into our DeFi development services, or if you want something unique, we can craft custom dApp development solutions just for you.

F. Compliance by Design: SOC 2 + ISO 27001 Evidence From Day One

Control Mapping: We've got this control matrix that lines up perfectly with the AICPA TSC (be sure to check out those updated 2022 points of focus!) and the ISO 27001:2022 Annex A. This guide includes 93 controls, and it’s got some cool new additions like Threat Intelligence, DLP, Secure Coding, and a few others. While we’re building, we end up creating a bunch of useful stuff like runbooks, logs, and SoA cross-references to help keep everything organized and running smoothly. If you want to dive into the details, just check this out here. It's a great resource!
Identity & Access: We’ve got Single Sign-On (SSO) and SCIM in play for all our consoles, and we make sure to stick to the least-privilege principle when it comes to managing our IAM for keys and contracts. We take great care in managing our deployments and make sure to keep our CMDB entries up to date. Also, we make sure to sync our change windows with segregation of duties and audit sampling. It helps us keep everything organized and in check.
How 7Block Can Help You: At 7Block, we’re really focused on making sure everything we build and operate is compliant. That’s why we provide security audit services to keep you headed in the right direction. We’ve got your back!

G. Procurement and ROI: A Business-First Delivery Plan

EIP-4844 Economics: So, here’s the scoop - Layer 2 solutions are now sending data as blobs to the consensus layer, and they’re pruning it after roughly 18 days. This is making rollup costs much cheaper compared to traditional calldata. Quite a game-changer, right? Here’s where you'll spot some really great short-term TCO wins! We take a closer look at the cost per transaction, analyze how changes in volume affect sales, and work out when we’ll start seeing a profit. (ethereum.org).
DORA-Aligned Delivery: First things first, we’ll set up your 5 DORA metrics. Our goal is to really tackle those pesky instability metrics, like the Change Fail Rate and Rework Rate, to help smooth things out. What's the plan? We want to make sure those go-lives are happening every week instead of just sitting around and waiting for those big quarterly launches. (dora.dev).
Observability ROI: So, here’s an interesting tidbit from Splunk’s 2025 report: companies that are nailing their observability game are seeing an incredible 125% return on investment. That’s pretty impressive! We can definitely adapt this model for your program! Our goal would be to cut down on downtime, speed up MTTR, and boost those conversion rates. (splunk.com).
How 7Block Can Help You: We’re all about getting you set up for success. Whether you need help creating a solid business case or getting ready to pitch to investors, our fundraising advisory has got you covered. And when it comes to delivering on your ideas, our blockchain development services are here to provide the support you need. We've got your back every step of the way!

Example 1: SAP S/4HANA Procure-to-Pay with L2 Settlement and Swift Rails

Trigger: When an invoice gets the green light in SAP, that’s when we start thinking about making a payment.
Flow: Alright, so first things first, let’s take a look at the supplier’s wallet with the Chainalysis API. If it raises any red flags, we’ll just move things over to escrow. (auth-developers.chainalysis.com). Alright, so here’s what we do next: we need to sign off on the USDC transfer using an OP-based Layer 2. Just a heads up, this is all backed by a KMS treasury policy. Oh, and make sure you use that PrivateLink-gated RPC while you’re at it! (aws.amazon.com). Once that's done, we send out a payment receipt to Substreams, then push it over to Kafka, and finally, it lands in our Splunk dashboards. Plus, we make sure to attach proof to the vendor record to keep everything nice and tidy for our audit trail. (docs.thegraph.academy). So, when we're dealing with fund products like money market tokens, we send subscription and redemption messages over Swift. We use the ISO 20022 standard and hook it up with Chainlink’s CRE/CCIP to make sure everything runs smoothly on a permissioned blockchain. (prnewswire.com).
Why it matters: So, after the Dencun update, you’ll notice that payment fees on Layer 2 are now just a couple of cents, while Layer 1 still charges way more. Plus, getting on board with ISO 20022 really simplifies things for the Treasury Ops team when it comes to bringing in new vendors. (investopedia.com).
Services: Take a look at what we’ve got for you! We offer blockchain integration and smart contract development. Let us help you navigate these exciting technologies!

Example 2: Intercompany Inventory Tokens Across L2s (AggLayer Unified Bridge)

Trigger: We’re starting the process of moving our tokenized inventory from Plant A on Chain X over to Plant B on Chain Y.
Flow: To kick things off, we're going to submit a unified bridge proof through AggLayer. Using a pessimistic proof variant is a great way to enhance safety, especially when you’re dealing with counterpart chains that aren’t completely zero-knowledge (ZK). It really makes a difference! (forum.polygon.technology). Next up, the substreams are going to kick off transfer events directly to the ERP using an SQL sink. Here’s something really awesome: we’ve managed to achieve a reconciliation SLA of under a minute when everything’s running smoothly! You can check out more about it here. Isn’t that impressive?
Why it matters: Building a common bridge makes a huge difference by reducing the need for complicated custom integrations. Plus, it helps us see the benefits of rolling out projects across multiple plants much faster!
Services: Take a look at our cross-chain solutions development and blockchain integration offerings! We’ve got some great options for you!

Example 3: Corporate Actions Automation for Asset Servicing

Trigger: So, when a company puts out news about a corporate action, it’s up to the asset manager to figure out how to divvy up allocations between different custodians and a tokenized fund.
Flow: First off, you'll want to use Chainlink CRE to double-check and confirm the actions pulled from those LLMs. It's a great way to ensure everything's accurate and reliable! Next, go ahead and shoot out those ISO 20022 messages to Swift. Don’t forget to update the on-chain status using CCIP while you’re at it! Take a look at this link: (blog.chain.link). You might find some interesting stuff there!
Substreams are gonna jump in and start sending NAV components straight to the portfolio systems. Plus, the DTCC Smart NAV pattern really sets us up with a solid and consistent on-chain data structure. If you're looking for more details, check out this link: dtcc.com. It’s got some great info!
Why it matters: Basically, this means you’ll run into fewer bumps in the road, can wrap up reconciliations faster, and reduce the chances of operational mishaps. Plus, you get to stick with the systems that your Operations team already knows like the back of their hand.
Services: Don’t miss out on our awesome asset-management platform development and dApp development services! Take a look!

Best Emerging Practices to Adopt Now

Focus on blobs, not just calldata: When working with rollups, it's really important to pay attention to blob availability fees. Make sure you’re adjusting your message sizes and how often you batch things together based on that. Get ready for a change in your unit economics in 2024! (galaxy.com).
Opt for OP-based L2s with live fault proofs (Stage 1): If it works well within your setup, definitely consider using OP-based Layer 2s that offer live fault proofs. Make sure to note down the governance revert path in your risk registers! It’s an important detail you won't want to overlook. (optimism.io).

Hey there! So, if you’re working with multiple L2s on Polygon, don't forget to consider the AggLayer Unified Bridge and those pessimistic proofs while you're mapping out your plans. It'll definitely make your life easier! You can try out local flows with AggSandbox to really get the hang of it. It’s a great way to play around and see how everything works! (docs.agglayer.dev).

**Use OZ v5. When it comes to transient storage and packing, using "x" can really help you cut down on gas costs. It's a smart move! Ditch the old. transfer/. Let's switch to custom errors to boost our efficiency, and while we're at it, make sure to send over those methods! (openzeppelin.com).
Go for stream indexing instead of polling: Check out Firehose or Substreams (or even Subsquid) for grabbing both real-time updates and catching up on historical data. It’s a smarter move! Hey, just a heads up--make sure to connect it to SIEM using the OpenTelemetry context. That way, everything runs smoothly! (docs.thegraph.academy).
Sanctions on both fronts: Make sure to set up those API pre-checks along with your on-chain oracles. This way, you’ll have a solid fail-closed strategy in place using Solidity. This gives you an extra layer of security. (auth-developers.chainalysis.com).
Private RPC as the default option: Take advantage of PrivateLink's cross-region endpoints and set up specific IAM policies for each service while also rotating your tokens regularly. Give your failover a try by using a DIN-style multi-provider mesh. This setup really helps keep everything running smoothly and adds an extra layer of reliability. (aws.amazon.com).
Stay on top of DORA's new instability metrics: Make sure to monitor the Deployment Rework Rate and include it in your change-advisory dashboards, right alongside the Change Fail Rate. It's a great way to keep tabs on how you're doing! (dora.dev).

GTM Proof Points You Can Take to the Board

Cost Basis: So, with the latest Dencun update and EIP-4844, Layer 2 transactions are now utilizing these blobs. The neat part? They get pruned after about 18 days, which helps keep things running smoothly! This has resulted in some pretty significant fee drops--like, we're talking a reduction of about 94-99%, depending on the specific Layer 2 and how busy it is. This could really change the game when it comes to cutting down on your cost of goods sold (COGS) for each transaction. If you want to dive deeper into it, check out this link here. It’s got all the details you’ll need!
Institutional Interop: So, here’s the scoop--Swift has announced that starting November 22, 2025, we can expect a worldwide shift to ISO 20022 for cross-border transactions. Pretty exciting, right? They've teamed up with Chainlink's CCIP to help make the whole integration process with bank partners a lot smoother, kind of acting as a go-between. This is definitely going to simplify things and make everything smoother! If you want to dive deeper into the details, just click here. Happy reading!

Hey there! Just wanted to give you a heads up that DORA is launching its 2024 update soon. This time around, they’re bringing in five important metrics, and one of the new additions is the Deployment Rework Rate. Exciting stuff! This gives us a really solid way to measure how efficient and reliable our software delivery is. Seriously, you should totally get your PMO in sync with this framework. It’s definitely a smart move! If you're looking for more info on this, you can check it out here. It’s got all the details you might need!

Observability ROI: According to Splunk's 2025 State of Observability report, the leading companies are raking in about 125% ROI from their observability initiatives. This boost comes from less downtime, faster recovery times, and an overall better experience for customers. Pretty impressive, right? We're using these figures to boost your business case! Check out the report here for all the details!
ZK Maturity: Check out zkVMs like SP1 Hypercube--they're really shaking things up! They can actually prove Ethereum blocks in less than 12 seconds and do it without breaking the bank, using around 275k gas for on-chain verification. How cool is that? This enables reliable computing exactly where it matters most. If you're curious to learn more about it, just check out this link here. It's definitely worth a look!

What a 90-day Pilot with 7Block Looks Like (Deliverables for Your RFP)

Weeks 0 to 2: Sketching Out the Architecture and Crafting a Security Plan. Let’s get started by setting up a VPC with PrivateLink. We'll also work on establishing a KMS key policy and signing flow, put some sanctions controls in place, and create a control matrix for SOC 2/ISO. Plus, we’ll set up a baseline for DORA. Sounds good?
So, the Statement of Work (SOW) is going to be closely linked with our blockchain integration and security audit services. It’s all part of how we make sure everything runs smoothly and securely!
Weeks 3-6: Getting the “Walking Skeleton” Set Up in Staging.
Alright, this is where the fun begins! We’re going to set up our contracts using OZ v5. Alright, here's the plan:

First off, we need to integrate a sanctions oracle. Then, we’ll get a Substreams or Subsquid pipeline up and running with Kafka/Postgres. After that, let's whip up some cool Splunk dashboards. And don’t forget, we should also prep those ISO 20022 test messages wherever they make sense! Hey, if you’re curious, take a look at the info on OpenZeppelin. There’s some cool stuff there!

Weeks 7 to 10: Focusing on Failover and Boosting Performance. We're going to concentrate on keeping everything running like a well-oiled machine. This includes working on multi-provider RPC failover tests, doing some throughput and load testing, setting up DORA instrumentation, and establishing Service Level Objectives (SLOs) along with error budgets.
Weeks 11-12: Compliance Package and Go/No-Go Decision. To wrap things up, we're going to put together a comprehensive compliance package. This will include a SOC 2 evidence bundle (the CC series), a mapping to the ISO 27001 Statement of Applicability, some thorough runbooks, a report on our disaster recovery test, and an ROI/TCO model for the executives. Sounds good, right?
