Book to see a discover and defend what you own with:

Monitor your external attack surface and dark web exposure from a single, easy-to-use tool
Assetnote combines market-leading discovery, enrichment, and vulnerability research to uncover hidden assets and subdomains before attackers exploit them – helping you focus on the highest-priority threats to your organization, the risks that keep your CEO, CTO, and CFO up at night, and take action to prevent cyberattacks.
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. Our Exposure Engine automatically cross-references your assets, including the specific 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 companies 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.

The only ASM that verifies exposures across your entire attack surface every hour
Threat actors are exploiting new exploits faster than ever. Assetnote automatically scans millions of assets from a single seed domain, simulating the tactics of a criminal to ensure you’re alerted first when credible threats are discovered, including:
- Continuous monitoring and discovery of external assets
- Detection of cloud services, third-party tools, and shadow IT
- Identification of ephemeral and risky assets
- Ongoing change monitoring and cloud integration for easy asset management
Defend your Attack Surface

Discover the blindspots in your public-facing attack surface – fast
Not all exposures are created equal. That’s why our ASM automatically detects and prioritizes vulnerabilities, end-of-life technologies, and cloud misconfigurations across your entire digital footprint. Our unique technology delivers only verified, version-specific exposures – meaning your team can focus on what matters most, respond faster, and reduce the risk of an attack.
See your real exposures now

Market-leading offensive security research, built in as standard
Our research team of ethical hackers continuously uncover new vulnerabilities in the tools you rely on. This gives our customers the advantage of being first to get notified with a proof of concept for every finding. Security teams can use these to act fast and remediate their exposure – long before the 90-day disclosure policy lapses and the patching scramble begins.
Stay ahead of zero-day threats

Helping security teams manage risk from a single ASM tool
Assetnote helps security teams by automatically mapping and filtering out noise, so you can focus on verified exposures that pose a real threat to your organization. Use it to:
- Enhance offensive security: Leverage zero-day research to scope pen tests, red teaming, and other security tests
- Strengthen product security: Control shadow IT, track assets such as APIs and third-party, technologies, and reduce your bug bounty spend.
- Optimize vulnerability management: Gain visibility into cloud assets, track regressions, and send findings directly to developers for swift fixes.
