Network Vulnerability Scanner for Public IPs and Servers

ScanTitan assesses a public IP address or server that you own or are authorized to test. It identifies the exposed services, matches detected versions to known CVEs and ranks the results by CVSS, EPSS and CISA KEV status. It does not scan internal networks or IP ranges.

Network Exposure Checker

Confirm permission to check .

Free public snapshot · Maximum 4 minutes Results may finish sooner. Unchecked areas are never treated as clean.

No account needed · Public targets only · No passwords, private addresses or network ranges

Quick-check results expire after 30 minutes and may reuse a result checked within the last 10 minutes. They are not automatically saved to an account. Sanitized target addresses and check activity are retained for 35 days for operations and the administrator daily summary. Addresses omit query strings and fragments; login details are not accepted. Advisory and network lookups may use public data services.

Public services and servers

A network vulnerability scanner built around public assets

A network vulnerability scanner checks the services a host exposes for known CVEs, misconfigurations and exposed services before an attacker reaches them. ScanTitan does this for individual public IP and server assets that you own or are authorized to test. It does not scan internal networks or IP ranges.

How to scan a network for vulnerabilities

Six stages, from adding the asset to a fix you can re-check. ScanTitan assesses the public IP or server you add.

Add a public asset

Add the public IP or server you own or are authorized to test. ScanTitan assesses that asset rather than sweeping IP ranges.

Identify exposed services

ScanTitan identifies the services reachable on the asset and the versions they report.

Match against known CVEs

Every detected service version is cross-referenced against published CVEs, so an outdated service becomes a named CVE with a CVSS score.

Add a Linux SSH assessment

On Business and Consultant plans, use the authorized Linux package inventory to identify eligible security advisories for installed packages. See authenticated Linux vulnerability scanning.

Separate what was observed

The report labels observations, potential CVE matches and results verified by a test, so you can see what each finding rests on.

Prioritize and remediate

Findings are ranked by CVSS, EPSS and CISA KEV status, each with a plain-language fix. Re-scan the asset after the fix to check it.

Network Vulnerability Scanner
Start from what is publicly exposed

Most breaches begin at the perimeter. ScanTitan assesses the public IP or server you add, so you see what an outsider can reach and which of it is affected by known CVEs.

Network You need both sides of the firewall
Fix the exploitable few, not the theoretical thousands

A network scan can return thousands of findings, and you will never fix them all. ScanTitan scores each on more than raw severity, combining CVSS with EPSS, the probability a flaw is exploited in the wild, plus exploit availability and host reachability. Read how vulnerability prioritization with CISA KEV and EPSS works.

A CVSS 7.0 on an internet-facing service with a live exploit outranks a CVSS 9.0 on an unreachable internal host. Each finding carries a plain-language fix, and a one-click re-scan verifies closure and attaches audit-ready evidence.

Ranked, not dumped, The top of your queue is genuinely the thing to fix first, so a two-person team gets the risk reduction of a much larger one.

Findings labeled by how they were established

✓
observations, potential matches and verified behavior

Network scanners can bury real issues under noise, and a lean team cannot triage a thousand maybes a week. ScanTitan labels each finding by what it rests on and ranks them using CVSS, EPSS and CISA KEV status.

Verified behavior is labeled

A result is marked as verified only when a test exercised the behavior. Version-based matches are shown as potential matches.

What was observed

Each finding states what the scan saw, so your team can confirm it on the asset.

Exploit signals

CISA KEV status and EPSS probability push the issues most likely to be exploited to the top of the queue.

Known CVE matching

Detected service versions are matched to published CVEs across vendors.

What ScanTitan's network scanner detects

From a known CVE on a public host to a database port open to the internet. Each check maps to how exposed servers actually get breached.

Known CVEs in Services & Software

Detected service versions are matched to published CVEs, including widely exploited ones.

Security Misconfigurations

Exposed databases, open management ports and unnecessary services that quietly widen your attack surface.

Linux SSH package advisories

On Business and Consultant plans, an authorized SSH assessment identifies eligible security advisories for installed Linux packages.

KEV status

Flags findings whose CVE appears in the CISA Known Exploited Vulnerabilities catalog.

SSL/TLS & Encryption

Expiring or misconfigured certificates, weak cipher suites, and deprecated protocols like SSLv3 and early TLS that break both security and compliance.

Outdated & End-of-Life Services

Flags services running unsupported software versions, a latent exposure even before a CVE is published, because unmaintained software is where the next one lands.

Cloud-hosted servers

A cloud-hosted server with a public IP is assessed like any other public server.

Authenticated Linux depth

An SSH assessment uses the authorized package inventory to find advisories an outside view cannot see.

CVSS + EPSS Prioritization

Every finding is shown with its CVSS score, EPSS exploit probability and CISA KEV status, so the top of your queue is the thing to fix first.

The network CVEs that breach companies

The vulnerabilities that cause real breaches are rarely exotic. They are often unpatched, internet-reachable services with public exploits. These are examples of widely exploited CVEs that affect network services.

Vulnerability CVE Affected service Severity
Log4Shell CVE-2021-44228 Apache Log4j (Java services) CVSS 10.0

What a ScanTitan network assessment report includes

Findings are grouped so the engineer who fixes the issue and the manager who reports the risk work from the same list.

Service inventory

The exposed services and reported versions found on the assessed asset.

Per-finding CVE detail

CVE ID, CVSS score, EPSS probability and CISA KEV status.

Basis for each finding

Whether the finding is an observation, a potential CVE match or verified behavior.

Ranked risk queue

Findings ordered by real-world risk so remediation starts where it matters most.

Plain-language remediation

A specific fix per finding. Re-scan the asset after the fix to check it.

Illustrative example: server.example.test
Reserved example name. Not a real scan.
POTENTIAL MATCH An SSH service reports a version affected by a published CVE
Version-based match. Review the CVE and confirm on the server.
OBSERVATION A database port is reachable from the internet
Seen by the scan. Decide whether it needs to be public.

Common questions about network vulnerability scanning

Answered by our security team, not by a chatbot.

No. ScanTitan assesses public IP and server assets only. It does not scan private networks, internal address space or IP ranges.

It uses the authorized package inventory of a Linux server you are allowed to test to identify eligible security advisories for installed packages. It is available on the Business and Consultant plans.

No. A scan result helps you find and fix issues but is not a compliance certification or attestation.

It depends on the job. ScanTitan is cloud-based and assesses public IP and server assets, with findings ranked by CVSS, EPSS and CISA KEV status. If you need to scan internal networks or run a scanner on your own hardware, a self-managed scanner may fit better.

Each finding is labeled as an observation, a potential CVE match or verified behavior, so you can see whether it is based on what the scan saw, on a version match or on a test.

IP / server assets are included in the Business plan, priced per asset place and billed annually. The pricing page lists current prices.

Internal or private networks, IP ranges and CIDR blocks, and router, switch or firewall credential checks are not covered. Each public IP or server is added as its own asset.

Is ScanTitan's network scanner right for you?

We would rather tell you now than after you have signed up.

Your public servers have open doors. Find them before attackers do.

ScanTitan assesses a public IP or server for known CVEs, misconfigurations and exposed services, labels each finding by how it was established and ranks them by CVSS, EPSS and CISA KEV status.
