What continuous offensive security testing is and how to implement it

Offensive Security

What continuous offensive security testing is and how to implement it

Introduction Continuous offensive security testing (COST) is a model for running adversary-style tests whenever something material changes, such as a release, a new internet-facing asset, or a change to a security control. Instead of the standard once a year test, Gartner introduced COST as a term to describe this trigger-driven intelligence-led approach. Escape's evidence standard supports that idea: a finding only counts after it has been reproduced in your own environment, with the requests

Pentesting

How to build a continuous pentesting program

Introduction An unpatched flaw is now the most common entry point for a breach, at 31%, ahead of stolen credentials at 13%, and the median time to fix one has crept up to 43 days (Verizon's 2026 DBIR). So an annual pentest is always a step behind, and you're two or three people being asked to test continuously with no budget to hire your way there. This is how to build a continuous penetration testing program without hiring more pentesters, by splitting the work so the part that scales runs its

Penetration testing as a service (PTaaS), explained

Offensive Security

Penetration testing as a service (PTaaS), explained

Penetration testing as a service (PTaaS) made buying a pentest almost frictionless. You scope it in a portal, watch findings land on a live dashboard, and click a button to retest the fix, all without a single procurement call. But the test still runs on a schedule, so weeks after it ends you get a report on a version of your app that shipped dozens of releases ago, and everything in between went out untested. PTaaS fixed how you buy a pentest, not when your coverage runs. This guide covers wha

Modern AI-powered Pentesting Tools In-Depth benchmark

If you're evaluating AI for offensive security right now, you're weighing two questions at once. The first: why not skip the tooling and point a frontier model at your apps yourself? The second: among the AI pentesting tools you could actually buy, which one earns the budget? We built this benchmark to answer both. Cascade, Escape’s multi-agent AI pentesting engine, went up against a single frontier model (Claude Opus 4.8) driven directly at the same targets. The only variable is the harness ar

Everything I Learned About Harness Engineering and AI Factories in San Francisco (April 2026)

I spent the last week of March 2026 in San Francisco talking to CTOs, CPOs, and engineering leaders from companies of every size about how they actually build with AI agents today. I've met solo founders of pre-series A startups, I attended Y Combinator DevTool Day on March 27 and All Things Dev on March 31, sat down with our advisors, and had dozens of conversations with founders and tool builders working at the frontier. This document is what I brought back. It is a field report: what

When it comes to securing applications and APIs, the best API security testing tools are indispensable. These advanced solutions detect vulnerabilities by continuously scanning for weaknesses and simulating real-world attacks. But how do you choose between all API security testing vendors? Agentless API security tools are transforming application security by overcoming the pitfalls of traffic-based solutions like Noname security (part of Akamai) or Salt Security, which burden teams with long s

Escape's DAST proprietary Business Logic Security Testing algorithm: what makes it innovative

Testing APIs for Business Logic vulnerabilities is hard. Actually, this is a mission that old-school DAST solutions like ZAP (formerly OWASP ZAP) cannot handle. I'm Antoine Carossio, passionate about Computer Science for more than 15 years now and cofounder & CTO of Escape. With my team, we've spent 3 years building a proprietary algorithm capable of finding Business Logic vulnerabilities in all API types, especially in the most recent ones like REST & GraphQL. However, simply stating its exis

Introducing Multi-User Testing with Natural Language Queries in Escape DAST

Most of today’s SaaS structures are multi-tenant environments. Making sure that each tenant’s data and resources are securely isolated from others is critical. Weaknesses or misconfigurations in tenant isolation can lead to unauthorized access or data leaks between tenants, compromising the security of the entire system. If you’re serious about maintaining strict isolation and protecting your tenants' data (so you can relax when the Thanksgiving madness hits), this product release is right up y

Gin & Juice Shop Benchmark: How DAST Tools Really Stack Up

This month, we set out to compare our DAST against some of the established names in Dynamic Application Security Testing. We’ve already benchmarked our scanner on vulnerable apps like VAMPI and DVGA, and now we’re putting it up against Qualys, ZAP, and Intruder (available in free trial) on Gin & Juice Shop. Why are we doing this? Our scanner uses in-house built web crawling and business logic testing algorithms, designed from scratch to handle modern applications. Naturally, we get asked “How d

In 2026, vulnerability scanning tools are essential for modern security teams, but running a scan is rarely the hard part anymore. The real challenge is automating it at scale: across thousands of assets, spanning APIs, web applications, and cloud services, in environments that can change by the hour. Security engineers are voicing this exact frustration. You can find it in multiple Reddit threads, like the one below, where a user asked how others automate vulnerability management in

How to Efficiently Implement DAST in CI/CD (2026 Guide)

Working with multiple customers implementing DAST in CI/CD has allowed us to learn a lot about what works, what doesn’t, and most importantly how to do it efficiently. The truth is, it’s not about adopting just any tool. It's about making testing for runtime vulnerabilities fit seamlessly into your existing workflow, without slowing things down or creating bottlenecks. The teams that succeed don’t just “plug in” a scanner, hope it works and just checks their box. They adapt their workflows, ch

The Paradox of Disabling GraphQL Introspection: Lessons from the Parse Server GraphQL API vulnerability

Last week, the security community was alerted to a vulnerability in Parse Server GraphQL API, which allowed public access to the GraphQL schema without requiring a session token or the master key. It is now identified as CVE-2025-53364. So, the question comes up: Should we disable introspection entirely in production environments to prevent such vulnerabilities? Having heard this question time and time again, I’ve already addressed it in past writings, and my stance remains: Disabling introspe
