What customers caught
MOVEit
CVE-2023-34362
Customers received alerts 2 days before MOVEit appeared in mainstream security news. Affected organizations had time to audit file transfer logs before their customers asked.
Snowflake
Credential stuffing, May 2024
When threat actors targeted Snowflake customer accounts, OpenPostern flagged unusual news signals within 6 hours. Customers reached out to their Snowflake reps before receiving vendor notification.
Okta
Support breach, Oct 2023
The Okta support system breach appeared in OpenPostern news alerts the same day Okta published their advisory. Zero lag between vendor disclosure and customer awareness.
Detection times are based on NVD publication timestamps and news monitoring. Past detection does not guarantee future detection.
OpenPostern connects to the same intelligence sources that enterprise security teams use: NVD CVE feeds, CISA's Known Exploited Vulnerabilities catalog, SSL and DNS infrastructure checks, and AI-powered news monitoring. For a fraction of the cost.
CVE monitoring you can actually act on
We pull from the NVD every day and cross-reference every vendor against the CISA Known Exploited Vulnerabilities catalog. If a CVE your vendor is exposed to is being actively exploited in the wild, you hear about it first.
Certificate and infrastructure checks
Beyond CVEs: we check every vendor's SSL/TLS certificate expiry, DNS configuration, and HTTP security headers on a continuous basis. Lapses that would fail a security review get flagged the day they happen.
Signal, not noise
Not every CVE is a five-alarm fire. Our scoring weighs your actual exposure against each vulnerability, so your inbox only gets what demands immediate action.
A risk score you can act on
Every vendor gets a 0-100 score updated daily: open CVEs, exploitability status, certificate health, all collapsed into one clear number. Trend arrows show you whether each vendor is getting safer or riskier over time.
Running in 60 seconds
Search our catalog by vendor name. We enrich each one automatically with category, domain, and historical exposure data. No integrations to configure, no security expertise required.
Built for businesses without a security team
Enterprise vendor risk management costs $550,000 a year in tools and headcount. We built the same protection for $79 a month. No CISO required.
Search for your vendors
Find vendors by name in our catalog. We automatically enrich each one with category, domain, and historical exposure data. No manual research needed.
We do the security work
Our engine scans CVE feeds, checks SSL and DNS health, monitors CISA's exploited vulnerability list, and reads security news through an AI lens. It runs continuously so you don't have to.
Act on what actually matters
Every alert is ranked by your specific exposure level. You get a clear action, not a security textbook to decode and not a raw CVE list to sort through.
The average cost of a third-party breach for an SMB is $550,000. Our Guard plan is $79 a month.
