Test the voice, endpoint and point-of-sale systems that sit outside the usual scope
VOIP, anti-virus and content filtering, client-side and EPOS assessments for the technology that is often overlooked.
Trusted by companies of all shapes and sizes
What is VOIP, endpoint and EPOS testing?
These assessments cover technology that is easy to leave out of a standard test. VOIP testing looks at voice systems for weaknesses such as call interception and toll fraud. Anti-virus, content filtering and client-side assessments check whether your endpoint protection and web filtering actually stop the threats they are meant to.
EPOS assessments review till and point-of-sale systems, including how they handle payment data and connect to your network. Results are reported in the Rootshell Platform with severity ratings and remediation advice.
The benefits of VOIP, endpoint and EPOS testing for your business
Bring the often-overlooked systems into the same view as the rest of your estate.
Identify potential vulnerabilities
Find weaknesses in voice platforms, endpoint controls, filtering rules and point-of-sale configuration.
Proactive defence
Check that your protective controls work as intended, rather than assuming they do.
Prepare for the unexpected
See how malware, a malicious attachment or a compromised till could be used against you, and how well it would be detected.
Better visibility and control
Track these often-separate systems alongside the rest of your results in one place.
Stay compliant
Provide evidence for standards that expect payment and endpoint systems to be tested, such as PCI DSS.

VOIP, endpoint and EPOS testing compared with standard infrastructure test
| VOIP, endpoint and EPOS testing | Standard infrastructure test | |
|---|---|---|
| Targets | Phone systems, user devices, tills and point-of-sale terminals | Servers and network services |
| Focus | Controls such as anti-virus and content filtering, and how devices behave | Reachable services and configuration |
| Typical findings | Weak endpoint controls, exposed phone services, insecure terminals | Open ports, missing patches, weak settings |
| Used together | Covers the places people and customers touch | Covers the core network |
Common questions about VOIP, endpoint and EPOS testing
What is EPOS testing?
EPOS means electronic point of sale, the tills and card terminals used to take payments. Testing looks for weaknesses in how they are set up and connected.
What does endpoint testing cover?
We check how well controls such as anti-virus, content filtering and client-side protections work on user devices.
Why test VOIP?
Phone systems can expose services, allow call fraud or give access to the network. Testing shows where.
Can this support compliance work?
Findings can feed into your wider compliance work. Ask us how a test fits your specific requirements.
