Agentic Development Security Picks Up Where Traditional Security Tools Leave Off

Janet Worthington 4 days ago
Let’s address the elephant in the room: Coding agents don’t generate secure code. Securing the AI-generated code is left as a separate activity, and it’s only part of the job. Coding agents also select dependencies, invoke tools, and execute tasks. Application security teams must govern those activities, protect the development and delivery environment, and validate […]

Your Application Vendors Control The Meter, The Gate, And The Referee

Faram Medhora 6 days ago
Tech executives keep asking, “Should we slow down AI adoption?” It is the wrong question. Your application vendors have already answered a more consequential one: how much autonomy your agents will get, what that autonomy will cost, and who will control it.

Turn Our Security Predictions Into Action

The next wave of AI risk won’t wait for static controls. Attend Security & Risk Forum November 9–10 to strengthen trust, build resilience, govern AI risk, and put stronger guardrails in place.

PHP2Shell Had Teeth, But The Real Story Is The Eclectic Mayhem

Erik Nost 6 days ago
The week of October 20 was unusually chaotic, even without the PHP news. Not only did teams need to scramble to identify and understand the impact of emergency PHP vulnerabilities, but there were also critical vulnerabilities in Node.js, cryptographically weak keys issues by a certificate authority, exploited vulns in network security equipment, and potentially accidental […]

Break Out Of The Vulnerability Matrix At Forrester’s Security & Risk Forum 2026

Janet Worthington October 29, 2026
Security teams are hearing two competing stories. In one, AI completely rewrites the rules of vulnerability discovery, exploitation, and remediation. In the other, AI simply adds speed and scale to problems that security programs already understand. The reality lies somewhere in between. Discovery Is Accelerating Faster Than Decision-Making AI analyzes code, generates findings, and proposes […]

PHP2Shell Leak Sends Security Teams Scrambling

Sandy Carielli October 22, 2026
At 14:00 UTC on October 21, PHP released patches to two critical CVEs, both of which can lead to remote code execution. CVE-2026-109618 addresses an RCE through an out-of-memory error, and CVE-2026-109619 addresses an RCE through a stale global-state issue. The flaws were discovered by researchers at Wiz and Calif, the latter as part of […]

Your Software Supply Chain Risk Doesn’t Stop At Your Suppliers

Janet Worthington October 15, 2026
Software supply chain security is no longer just about knowing which open-source libraries are in your applications. Attackers are compromising developer environments, build systems, trusted distribution channels, and even security tools such as container security and infrastructure-as-code scanning tools. AI now adds another layer of dependencies to evaluate and protect. The result is an interconnected […]

Talk To Your Vendors About Quantum Security Readiness

Sandy Carielli October 7, 2026
Last month, CISA and the G7 Cyber Security Working Group put out a call to action for post-quantum readiness, listing five priorities to help with migration. It’s particularly welcome to see CISA and the working group highlight “integrating PQC into cybersecurity requirements and procurement processes” as one of the priorities. At the beginning of this […]

It’s An Agent’s World: Customer Insights From The Forrester Wave™: Bot And Agent Trust Management Software, Q2 2026

Sandy Carielli September 18, 2026
One of the best parts about authoring a Forrester Wave™ is getting to speak to customer references. Every vendor in the Wave evaluation connects me with customers who talk about how they use the product, what they like, and what they wish was better. While a lot of that goes into evaluating vendors during the […]

Intent Is The New Epicenter Of Agentic Security

Jeff Pollard August 31, 2026
Cybersecurity spent decades trying to stop things from happening, identifying them, and then investigating what happened. Agentic AI challenges us with a much more difficult question: What was the system trying to do? Agents don’t just execute instructions. They interpret objectives, select tools, access data, cross systems, and change tactics. In most cases, a user […]

Turn AEGIS Controls Into An Agentic AI Security Stack

Jeff Pollard August 21, 2026
Agentic AI creates control, technology, and purchasing problems. Security leaders need to know the controls that they must satisfy, the technologies that can satisfy them, where existing tools already provide coverage, and where a new investment actually fills a gap. Far too often, we see clients conducting that process in reverse order … trying to […]

The Future Of AppSec May Be Autonomous, But The Present Is Surprisingly Practical

Janet Worthington July 29, 2026
AI is no longer a future feature in application security; it is rapidly becoming a core part of how application security (AppSec) tools identify, prioritize, and remediate risk. Yet despite aggressive vendor investment, adoption remains constrained by trust concerns, questions about value, and uncertainty about pricing models. In our new report, The State Of Artificial […]

Move Over, WAF: The Web Application Protection Platform Takes Over

Sandy Carielli June 3, 2026
For years, the web application firewall (WAF) has been a foundational control for protecting customer‑facing digital experiences. It started as a compliance-driven application security tool that filtered malicious traffic, blocked common exploits, and provided a last line of defense in front of web applications. But the way applications are built, deployed, and attacked has fundamentally […]

OpenAI’s Daybreak Promises To Improve AppSec But Introduces A New Pricing Model: Five Buyer-Side Implications For CISOs

Jeff Pollard May 13, 2026
OpenAI recently announced Daybreak, its vision for making agentic application security faster and more capable. While promising, Daybreak will also make security more expensive per unit of work. In this model, customers will pay for tokens and multiagent workflows burn tokens. CISOs and CIOs should budget for application security (AppSec) line-item inflation, not deflation, with […]

Not A Vendor, Still A Breach: Vercel’s Third-Party Risk Failure

Alla Valente April 27, 2026
Some security incidents are complex. The Vercel incident is more troubling because it was predictable. The attackers did not exploit a procurement gap. They exploited a definition gap. Here’s what happened. A Vercel employee signed up for Context.ai’s AI Office Suite using a corporate Google account and clicked something effectively equivalent to “Allow All,” granting […]
