Take back control of your attack surface management

Daily scans leave your attack surface exposed

Most ASMs only scan your assets daily (or even weekly) leaving you exposed between a vulnerability's introduction and its detection. With our hourly scanning, you can close that gap – mitigating exposures faster than attackers can exploit them.

Unverified vulnerability alerts cost your team time

An exposure doesn’t always mean there’s a risk to your organization. That's why we automatically cross-reference assets, including the versions you are running, to verify exposures – checking they are legitimate – before alerting your team.

Third-party data lags behind true risk

Relying on third-party and publicly disclosed vulnerability data leaves tou open to risk. Our research team actively hunts for vulnerabilities in the vendors you rely on – alerting you to them so you take action and defend your infrastructure – often months ahead of a patch being released.

Searching for Attack Surface Management vendors? We’ve got you covered

Assetnote continuously enriches every discovered asset with extensive metadata, including open ports, running technologies and versions, DNS records, SSL certificate details, ASN and WHOIS data, application screenshots per port, page network requests, and API discovery – all updated hourly to give your team actionable context.

Monitor your entire attack surface. Filter out the noise

Assetnote goes beyond an IP-centric discovery to deliver you a complete and accurate asset inventory – including cloud and CDN-hosted assets. Our platform automatically de-duplicates your results and filters out the noise like wildcard DNS and passive DNS list, so you see only what’s real, relevant, and exposed.
