Deepinfo vs. Tenable

Tenable suits organizations whose first need is vulnerability management inside the network, with its exposure platform extending out from there. Deepinfo suits teams that start from the outside: every internet-facing asset, the credentials and lookalike domains around it, and the vendors connected to it.

They are built from opposite ends, which is why the two can sit side by side.

Where Tenable Is Strong.

Inside the network, Tenable is hard to displace.

Nessus, agents and internal scanners make up a mature vulnerability management practice, and Tenable One carries it into cloud, identity and operational technology. VPR adds a predictive rating of its own on top of CVSS.

Deepinfo does not scan inside your network and does not try to replace that work.

Where Deepinfo Is Strong.

Deepinfo is built for the part of the surface your internal scanners never had a seed for: subsidiary domains, inherited infrastructure, forgotten staging hosts. Discovery pivots across Deepinfo’s own index by IP address, mail server, name server and WHOIS registrant.

Every CVE on those assets shows CVSS, EPSS and CISA KEV side by side, so your team can see why an item sits at the top of the queue.

  • Each asset scanned layer by layer, with a history per layer
  • Issues tracked through to verified resolved
  • Issues classified against compliance frameworks

What Buyers Ask About Both.

Does Deepinfo replace Tenable?

Not for internal vulnerability management. Deepinfo covers the outside: internet-facing assets, leaked credentials, lookalike domains and vendors. If you already run Tenable internally, Deepinfo adds that view without changing your scanning.

Tenable has an attack surface product too. How do they differ?

Both discover internet-facing assets from an internet-wide dataset. Deepinfo adds scanning with a history for each layer, CVSS, EPSS and CISA KEV side by side, and breach, lookalike and vendor monitoring on one platform. Run both on the same seed domains and compare.

Can Deepinfo’s discoveries feed our internal scanning?

Yes. Assets export through the EASM API by filter, as JSON or CSV, so hosts that were never in your scan scope can be handed to the scanners you already run.

How do finding states compare?

Tenable tracks vulnerabilities as new, active, resurfaced and fixed. A Deepinfo issue moves from newly_detected to verified_resolved once a rescan confirms the fix, can be closed as risk accepted or a false positive, and reopens as reappeared if the signal returns.

How do Deepinfo findings reach our other tools?

Through the REST API, event notifications and scheduled PDF reports. The integrations page lists current connection options.
