Minimizing attack surface > all security certifications
𝐄𝐧𝐡𝐚𝐧𝐜𝐢𝐧𝐠 𝐒𝐞𝐜𝐮𝐫𝐢𝐭𝐲 𝐢𝐧 𝐅𝐢𝐧𝐭𝐞𝐜𝐡: 𝐌𝐢𝐧𝐢𝐦𝐢𝐳𝐢𝐧𝐠 𝐀𝐭𝐭𝐚𝐜𝐤 𝐒𝐮𝐫𝐟𝐚𝐜𝐞𝐬 TL;DR: • Security certifications alone are not enough to prevent attacks. • The best way to secure data is to minimize the attack surface. • Self-hosting tools can significantly reduce the risk of data breaches. I recently received a letter from my bank stating that I should ‘not worry; my account was safe.’ This immediately worried me. The email mentioned a data breach at a partner bank that may have exposed our account information. This attack was impressive in scale. Evolve Bank and Trust, the bank behind finance apps such like Mercury, Affirm, and Wise, was compromised. The attackers stole a whopping 33 terabytes of data-roughly equal to half the online data from the Library of Congress. This likely represents almost the entirety of Evolve’s Azure Cloud storage. The troubling aspect of this breach is that Evolve Bank and Trust had all the expected security certifications, including SOC 2 Type II, HIPAA, HITRUST CSF, and PCI DSS. Despite these certifications, the attackers still managed to infiltrate their systems. Although we still don't know how the attackers breached Evolve, this incident highlights the importance of robust security practices. Architecting secure systems involves many principles, but the best way to secure data is not exposing it in the first place, thereby limiting the attack surface. The attack surface is the sum of points where an attacker can attempt to enter or extract data from an environment. Reducing this surface is crucial as it limits the potential entry points an attacker can exploit. In 2022, the financial sector experienced 566 data breaches, exposing over 254 million records. This statistic highlights the critical need for enhanced security measures in the fintech industry. In fintech, where the stakes are high, minimizing the attack surface is crucial to reducing breach risks. The safest data is not connected to the public internet. While cloud-based applications are convenient, they often overlook the need to limit the attack surface, regardless of the vendor's certifications. Hosting a service on-premises is the best way to add functionality without increasing your attack surface. Self-hosting tools, whether air-gapped or behind your firewalls, can significantly reduce vulnerabilities. This approach doesn't impede innovation; most systems, including GrowthBook's feature flagging and A/B testing platforms, offer self-hostable solutions. By adopting self-hosting, you maintain security while leveraging the best tools available.

We’re pleased to announce GrowthBook 3.0! This release has a lot of huge new features which you can read about on our blog: https://lnkd.in/eUp4jQ66 or see some highlights below. Edge SDKs We’ve developed SDKs that seamlessly integrate with your CDN Edge, allowing you to conduct experiments directly on edge workers. With dedicated SDKs for Cloudflare Workers, Lambda@Edge, Fastly Compute, and others, you can now run client-side tests (including visual editor tests, URL redirects, and feature flags) without any of the typical issues they have, including ad blocks and flickering. Explore the documentation here: https://lnkd.in/ezDEB4PY. Bayesian Priors and CUPED We reworked our Bayesian statistics engine to support increased accuracy, support for priors, and CUPED variance reduction. You can read more about the Bayesian changes on our blog: https://lnkd.in/eZm6SqJy Custom Roles A long-awaited enterprise feature, you can now define custom roles with exactly what permissions they can or cannot have and then assign those roles to users or teams. This feature empowers you to tailor roles to your team's specific needs. View the Custom Role docs for more details: https://lnkd.in/eJGTC9ZM OpenFeature Support We’re excited to join the OpenFeature ecosystem with an official GrowthBook Provider! This initial release adds support for the Web and React SDKs, but we plan to add providers for all supported languages soon, so stay tuned! Experiment Slack/Discord Alerts We’ve added experiment warning alerts for when there are errors or warnings with your experiments JSON Feature Flag Editor You can now define exactly what fields you want to pass with the feature flags, resulting in a user-friendly UI with full validation. New Next.js Examples We’ve updated our Next.js examples to include all the new rendering strategies available with the Next 14 App Router. We show how to use GrowthBook inside of React Server Components, how to integrate with the built-in fetch cache (with webhook revalidation), plus a powerful hybrid strategy that lets you do client-side feature flagging without any client-side network requests! Check out the repo: https://lnkd.in/eJh5Hxzv SDK Updates The GrowthBook team and community have been hard at work creating and improving our SDKs. We’ve added a new React Native SDK, completely refreshed the Elixir, GoLang, and C# SDKs, and improved the Java, Python, Ruby, JS, React, Flutter, Swift, and Kotlin SDKs.

We’re proud to announce the release of GrowthBook 2.9, with many highly requested features, including Feature Flag Approvals, URL Redirect Testing, and Quantile Metrics. More details below or on our blog: https://lnkd.in/ecJf5Bzk URL Redirect Testing One of the most common use cases for A/B testing on the web is to compare two versions of a page, hosted on different URLs. With this update, GrowthBook has native support for URL redirect tests. All you need on your site is the latest version of our JavaScript, React, or new HTML Script Tag SDK Quantile Metrics (Median, P99, and more) We’re proud to announce that GrowthBook is the first experimentation platform to fully support Quantile metrics. You can now report on things like P99 Latency, Median purchase price, and even use quantiles for decomposition deep dives! Feature Flag Approvals GrowthBook now supports advanced approval flows for feature flag changes. It behaves similarly to GitHub - make a change in a new draft revision, mark it as “ready to review”, another person on your team reviews it and decides whether to approve, request changes, or just leave a comment. Project-scoped Attributes and Environments Now, you can restrict attributes and environments to a subset of your projects, simplifying the GrowthBook UI and reducing the chance for typos and mistakes. Plus, when combined with project-scoped roles, you now have fine-grained control over exactly who is able to manage which attributes and environments. New HTML Script Tag SDK There’s a brand new GrowthBook SDK available, perfect for all low-code websites (Webflow, Shopify, Wordpress, and more). All you have to do is add a single `<script>` tag to your website and you’ll get support for our Visual Editor, new URL Redirect tests (see above), and even Feature Flags! No configuration is required (although there are lots of knobs and switches for those that want them). New and Improved Webhooks with Slack/Discord Support We’ve revamped our event webhooks with more powerful filtering. Want to trigger a webhook for all feature flags that change in `production` with the tag “important”? You can do that! To make integration easier, there’s a new Formatter option to automatically render the webhook in a format that Slack or Discord understands.

We have just released GrowthBook version 2.8. This release includes prerequisite flags, feature flag code references, version-controlled metric support, no-access user roles and more. Read more about the changes below or on our blog: https://lnkd.in/eX5_7CKj Prerequisite flags With Prerequisites, you can group together related feature flags and describe complex relationships between them. For example, you can have a bunch of features that all reference a `release-2.8` parent flag as a prerequisite. The child features will only be enabled when the parent flag evaluates to 'true.' This also unlocks a bunch of more advanced use cases, which you can read on our blog. Official (Version Controlled) Metrics It’s not uncommon for large organizations to have hundreds or thousands of experimentation metrics. These are often a mix of “Official” metrics (widely used and vetted by the data team) and Ad-Hoc metrics (one-off, created by a product team, etc.). GrowthBook 2.8 introduces a brand new workflow that can make this distinction clearer and lead to more trustworthy experimentation. You can now store your Official Metric definitions as code in a version control system like GitHub and changes can be automatically synced to your GrowthBook account. Feature Code References In version 2.6 we released stale feature flag detection. Now with Code Refs you to keep track of feature flag usage by showing you exactly where each flag is used in your code. “No Access” Role In previous versions, the lowest role you could grant someone in your GrowthBook account was “readonly”. This meant that every user you invited to your organization could, at the very least, see every single feature flag, experiment, etc., in your account. GrowthBook 2.8 introduces a new role called “No Access”. As the name suggests, this is even lower than “readonly” and essentially grants no permissions whatsoever. When combined with project-scoped roles, this becomes super powerful. For example, grant someone a global role of “No Access” and then override this with a more permissive role for specific projects. Webhooks for SDK Connections Every SDK Connection in GrowthBook gets a dedicated API endpoint that returns a JSON payload of all included feature flags and experiments. You can now attach Webhooks to an SDK Connection so you can be alerted any time this payload changes.
