Pick the right aisle
ZeroDayTracker vs the $9–$80/month shelf.
We are not a CVE encyclopedia, a scanner, or a six-figure intel platform. These pages say when to buy us and when to buy them.
OpenCVE
OpenCVE alternative for SaaS stacks
OpenCVE is the right tool if you want to search 350k CVEs, self-host, and run SOC remediation workflows. ZeroDayTracker is the right tool if you want CISA KEV alerts on the SaaS you actually pay for, without standing up another platform.
Sentrytex
Sentrytex alternative: KEV watchtower vs breach-news monitoring
Sentrytex and ZeroDayTracker sit on the same shelf: name your SaaS stack, get alerts, skip the six-figure intel platform. Sentrytex leans into vendor breach news. We lean into CISA’s Known Exploited catalog and the vendors behind your vendors.
vulntracker.io
vulntracker.io vs ZeroDayTracker: every CVE vs exploited-first
vulntracker.io is a CPE watchlist for people who want every CVE on the software they run. ZeroDayTracker is a KEV watchtower for people who want to know when CISA says a tool in their SaaS stack — or the vendor behind it — is being exploited.
