Internal Vulnerability Scanning · VM
An attacker who gets inside your network needs vulnerabilities to move through it..
What is Internal Vulnerability Scanning?
Internal Vulnerability Scanning maps the weaknesses across your internal network: unpatched systems, misconfigured devices, and overlooked endpoints that attackers can exploit after gaining initial access. Most breaches move laterally once inside. Internal scanning ensures your exposure picture covers both.
How does BlackstoneOne help?
BlackstoneOne scans your internal infrastructure to uncover weaknesses not visible from the outside. We scan for misconfigured assets, unpatched devices, and exploitable services to show where attackers could move if they get past your perimeter.
What we scan internally
Everything inside your network that could be exploited..
Unpatched systems
Operating systems and software with known vulnerabilities that have not been updated. The most common entry point for lateral movement.
Misconfigured devices
Routers, switches, printers, and endpoints with insecure default settings or improper access controls that open pathways through your network.
Exploitable services
Internal services running on vulnerable versions or with unnecessary privileges that attackers can use to escalate access.
Overlooked endpoints
Old workstations, dormant servers, or IoT devices that still have network access but no active oversight.

Of successful breaches involve lateral movement through the internal network

Frequently asked questions
Common questions about Internal Vulnerability Scanning..
Is internal scanning different from external scanning?
Yes. External scanning looks at what's visible from the internet. Internal scanning maps weaknesses inside your network that attackers exploit after gaining initial access. Both are needed for complete coverage.
How does BlackstoneOne connect to our internal network?
BlackstoneOne uses appliances installed on individual network segments. This ensures scans are contained within each segment and do not cross your segmented network boundaries.
How quickly can we get started?
You can add targets and kick off your first internal scan within minutes. Findings are prioritised by risk, threat, and context and ready to share within hours.
