For buyers, not a blog
How to watch KEV without a threat-intel desk.
Each guide answers a query people already type before they pay $20. No thought leadership about the future of zero-days.
CISA KEV alerts
How to get CISA KEV alerts without a SIEM
CISA’s Known Exploited Vulnerabilities catalog is a public JSON feed. Here is how to get alerts for your SaaS stack without Elastic, Sentinel, or a six-figure intel platform.
Signal vs noise
CISA KEV vs NVD: what a CIO should actually watch
NVD is the encyclopedia of CVEs. CISA KEV is the short list of vulnerabilities being exploited. A CIO without a SOC should watch KEV first, then critical CVEs on named SaaS vendors.
Patch priority
Why a CVSS 10 can wait and a KEV 7.5 cannot
CVSS measures severity in a lab. CISA KEV measures exploitation in the world. Patch priority for a SaaS-first company should follow known exploitation, not the bigger number.
BOD 22-01
CISA BOD 22-01 for companies that are not federal
Binding Operational Directive 22-01 orders federal agencies to remediate KEV entries by a due date. Private companies are not bound — but the catalog is still the right patch list. Here is how to use it without pretending you are an agency.
Postmortem
CitrixBleed and MOVEit: what a stack watchtower would have shown
CitrixBleed and MOVEit were not subtle. They were KEV-class events on products companies forgot they still ran. A SaaS watchtower does not replace patching — it names the blast radius on the day CISA does.
SaaS watchlist
A CVE watchlist for a SaaS stack (not a scanner)
How to monitor Okta, Slack, Salesforce, and M365 for exploited vulnerabilities without an agent, CPE database, or vulnerability scanner.
Zero-day alerts
Zero-day alerts for a SaaS stack (without ranking for “zero-day tracker”)
True zero-days are rare in public feeds. For SaaS buyers, “zero-day alerts” should mean known-exploited (CISA KEV) plus critical CVEs on named vendors — not another research tracker.
Blast radius
Supplier blast-radius: when AWS is exploited and you only listed Slack
SaaS risk is not only the logo on the invoice. Parent companies, cloud hosts, and identity providers are how KEV entries miss a naive watchlist. Here is the graph ZeroDayTracker uses.
