A correlation rule joins several telemetry sources and fires when they agree. Guidance on writing them concentrates on thresholds, ordering and tuning for noise. ‍ The decision that determines whether a rule works is upstream of all of that. Each source in a rule plays one of three roles, and treating them interchangeably is what produces a rule that misses real events or fires on ones nobody can act on. ‍

A breach response begins with a record count and a notification assessment. How many individuals, in which jurisdictions, under which statute. ‍ Some organizations hold almost no personal data and enormous quantities of other companies' commercial confidences. An insurer's claims files contain policyholders' loss histories, control failures and settlement amounts. The statutory machinery may not engage at all, and what engages instead is a contract portfolio. ‍

Third-party code now accounts for 66% of the most dangerous, long-lived vulnerabilities across application portfolios, according to Veracode’s 2026 State of Software Security Report. For AppSec and engineering leaders, that stat tells a familiar story: shrinking release cycles, expanding open-source dependency footprints, and mounting regulatory pressure.

Citrix disclosed two critical vulnerabilities in NetScaler ADC and NetScaler Gateway that are already being exploited in the wild. CVE-2026-88771 allows unauthenticated attackers to run commands on an affected appliance, while CVE-2026-88772 can lead to remote code execution or denial of service when DTLS is turned on. Both received a CVSS v4.0 score of 9.5, and CISA added them to its Known Exploited Vulnerabilities catalog.

Mistaking a lack of alerts for a lack of threats is a dangerous assumption. But in the world of dark web exposure, silence is rarely a sign of safety; it’s a blind spot. Relying on external alerts to discover your vulnerabilities means you are reacting far too late. Here are five questions you should answer that turn that assumption into something you can measure. If you answer "no" or "not sure," treat it as a blind spot that a dark web scan will address.

Most attack surface management (ASM) evaluations start with a name already on the table: a vendor from a G2 grid, an analyst shortlist, an inbound email, or a renewal conversation. Before you commit to a proof of concept (POC), you need to know how it compares. This page provides a capability matrix across 10 ASM vendors, followed by an honest section on each. UpGuard makes one of the platforms on this list, so every section, ours included, covers where the product isn't the right fit.

The headline change in Europe's network security directive is scope. Directive (EU) 2022/2555 reaches an estimated hundred and sixty thousand entities across eighteen sectors, roughly ten times what its predecessor covered. ‍ The more consequential change is who decides. Under the previous regime a member state identified operators of essential services individually, through an assessment of criticality and dependency.

Sending privileged material through an external AI service is a disclosure to a third party, and voluntary disclosure to a third party waives privilege. The reasoning is straightforward and a federal court has now applied it. ‍ A second federal court reached the opposite conclusion on the same question within days, on a distinction the first did not draw. The position is genuinely unsettled, and the parts that are settled point at configuration choices rather than at a prohibition. ‍

Almost every obligation in the AI Act is keyed to a risk classification. Work out which tier a system falls into and the duties follow. ‍ Article 4 is not. It applies to providers and deployers of any AI system whatever it does, its subject is people rather than systems, and national authorities began supervising and enforcing it from 2 August 2026 while the high-risk regime moved to December 2027. It is the live one, and it sits outside the structure most governance programs are built on. ‍
