Stop drowning in CVEs.
Track only the ones that hit your stack.
Nearly 10,000 vulnerabilities are published every month. You only care about the ones affecting the vendors you actually run. We send you an email the moment a CVE touching your stack is confirmed exploited.

The problem every defender knows
New CVEs published every month. No human can read them all.
Actually get exploited in the wild. The rest are noise for most teams.
Or less — how fast attackers weaponize many CVEs after disclosure.
The signal is buried in the noise. By the time you spot the CVE that matters, attackers may already be exploiting it. You need a filter that watches for you.
How it works
Pick your vendors
Select the technology in your environment — Cisco, Microsoft, Fortinet, VMware, and more. Free tier covers up to 3 vendors.
We watch 24/7
Our CVE Watchtower cross-references the CISA KEV catalog and EPSS exploitation scores against your watchlist, checking every 30 minutes.
You get the alert
When a CVE affecting your stack is confirmed exploited or crosses the exploitation threshold, you get a clean email — often within hours of disclosure.
Set up your free alerts
Select your vendors, enter your email, and confirm. That’s it. No credit card, no spam — just the CVEs that matter to you.

Frequently asked questions
Is it really free?
Yes. The Free tier covers up to 3 vendors with KEV and EPSS alerts, forever, with no credit card required. Paid tiers add unlimited vendors and extra features, but the free tier is fully functional on its own.
How fast will I get alerted?
Our system checks the CISA KEV catalog and EPSS scores every 30 minutes. When a CVE affecting your vendors is confirmed exploited, you’ll typically receive an email within an hour — often faster than mainstream security news covers it.
What’s the difference between KEV and EPSS?
KEV (Known Exploited Vulnerabilities) is CISA’s catalog of CVEs confirmed to be exploited in real attacks. EPSS (Exploit Prediction Scoring System) estimates the probability a CVE will be exploited soon. We alert on both, so you catch threats that are already active and ones about to become active.
Will you spam me?
No. You only receive an email when a CVE actually matches your watchlist. On a quiet week, that might be zero emails. Every message includes a one-click unsubscribe link.
Can I change my vendors later?
Yes, anytime. Free users can adjust their 3 vendors from the confirmation email. Pro and Team members manage an unlimited watchlist from their account settings.
Who runs this?
Daily CyberSecurity (securityonline.info) is an independent cybersecurity publication that has tracked vulnerabilities and published CVE analysis for years. CVE Alerts is powered by our in-house CVE Watchtower database.
