Honest comparison
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.
Sentrytex is a trademark of its owner. Their site. Facts from public pages as of 2026; products change.
| Feature | ZeroDayTracker | Sentrytex |
|---|---|---|
| Primary signal | CISA KEV + critical NVD | Vendor breaches + KEV + NVD + GHSA |
| Supplier blast-radius | Parent / cloud / identity graph | Per-tool monitoring; not the same graph |
| Setup | Curated catalog, no agent | Select SaaS tools, no agent |
| Public tracker | SaaS-matched KEV index | Marketing site + product alerts |
| Price | Free / $20/mo | From $9/mo after trial (card required on trial) |
Both products assume you do not have Mandiant on retainer. Sentrytex’s homepage is about breach cost and disclosure clocks. Ours is about CISA required action on the tools that hold your data. Read both. The overlap is real; the feed priority is not.
A vendor status page will not tell you that Slack’s cloud host is in KEV. Our Keep Track plan will. That fan-out is the feature Sentrytex does not advertise, because it is not their product.

No. We do not scrape disclosure blogs as a primary feed. If the incident is in CISA KEV or a critical NVD CVE that matches the catalog, it shows up. Operational breaches without a CVE do not.
If your fear is “Okta/Slack/AWS is in KEV and nobody told me,” buy ZeroDayTracker. If your fear is “our PaaS was breached and the CVE is a week away,” Sentrytex is built for that.
Three tools free. Keep Track is $20/month for supplier blast-radius, full history, and a digest.
