How does blacklens.io compare vendors?

We compare verifiable criteria in these areas: attack surface and early warning, vulnerability management, penetration testing, dark web and supply chain, analysis and platform. Details on blacklens.io come from the product and its documentation. Details on other vendors come from publicly available information such as websites, datasheets and documentation.

Why are there no scores or rankings?

Because solutions are built for different jobs. A specialised dark web service is not a weaker vulnerability scanner, it has a different focus. The comparison therefore shows what is included and names each solution's strengths, including where another vendor offers something blacklens.io does not.

What do “partial” and “no public information” mean?

“Partial” means a feature is available with limitations, as an add-on module or depending on the licence. The note in the cell names the condition. “No public information” means public sources neither confirm nor rule out the feature.

Can blacklens.io be combined with other solutions?

Yes. blacklens.io offers a REST API with more than 250 endpoints, a Microsoft Sentinel solution and integrations for Jira, ServiceNow, Microsoft Teams, Slack and webhooks. Findings flow into existing SIEM, ticketing and alerting processes, even if you keep a specialised solution for some areas.

A detail is out of date. How do I report it?

Feature scope and licences change continuously. Write to hello@blacklens.io and name a public source. We check the detail and update it in German and English with a new as-of date.
