Confidential computing is essential when an organization needs to process sensitive data on infrastructure where the operators should not have access to it.

On September 27, 2026, Citrix published a security bulletin covering eight new vulnerabilities in NetScaler ADC and NetScaler Gateway. Some of these vulnerabilities are critical and have already been exploited in the wild. Citrix released fixed NetScaler builds and recommends upgrading affected appliances as soon as possible. However, when a vulnerability is already being actively exploited, installing the update only solves part of the problem.

If you run CertKit across multiple collections, September was your month. The new home page lets you search across all of them, the new dashboard surfaces the context you need, and a read-only API pulls it all into your external tools.

SAST vs SCA vs DAST vs IAST: a clear breakdown of what each scan finds, when to run it, and how to combine them across your SDLC. Most AppSec teams don't run one type of scan - they run several, at different points in the pipeline, because no single tool sees the whole picture. This article breaks down SAST vs SCA vs DAST vs IAST: what each one actually tests, where it fits in the software development lifecycle (SDLC), and how to combine them without duplicating effort or drowning developers in findings.

Interactive Application Security Testing (IAST) finds vulnerabilities in running applications by monitoring code from the inside. Learn how it works and where it fits. Interactive Application Security Testing (IAST) is a method for finding security vulnerabilities in an application while it's running, by instrumenting the code and observing how it behaves during normal use or testing.

At Tigera, we spend a lot of time thinking about agent security: identity, policy, runtime controls, and the record left behind after an agent acts. Coding agents create an interesting problem because, in most organizations, they didn’t arrive through the front door. Few companies ran a platform evaluation and rolled Claude Code out to 500 developers. Developers installed it themselves.

Technically: no. In practice: maybe. Lot’s of teams are experimenting with shorter duration certificates from Let’s Encrypt to get ready for the 47-day mandate. Those certs come with a big gotcha: no more Common Name. A modern browser is perfectly happy with a TLS certificate that has no Common Name. Your VPN or mail server might have other opinions. And since those are probably things you’d like to keep working, there’s a little more nuance to the answer.
