About
Specialists in the security of the systems your business talks through
GoldAgent focuses on one thing: the security of PBX, SIP and VoIP telephony. It is the layer most security programmes overlook, and one that attackers routinely turn into fraud.
GoldAgent is a UK specialist in authorised PBX, SIP and VoIP security, based in Bristol. We assess the telephony layer that most security programmes miss. Work is authorised only. Website security issues should be reported via the contact form. Assure is the flagship annual programme; MSP white-label is available where commercially agreed.
Why we exist
Telephony is a security blind spot
Most organisations run a vulnerability-management programme for their servers, endpoints and web applications. Very few extend it to the phone system, even though the PBX is internet-connected, carries every call, and is a direct route to fraudulent spend the business usually has to pay for.
Generalist penetration testing rarely covers SIP, trunking, extension security and toll fraud in depth. GoldAgent exists to close that gap: specialist, authorised telephony security assessment, with findings a decision-maker and a technical team can both act on.
What we stand for
- Authorised testing only, never anything else
- Evidence before assertion, no invented findings
- Human validation over raw scanner output
- Honest, plain reporting, no fear marketing
- Specialist depth over generalist breadth
How we're different
Specialist, not generalist
Telephony depth
We assess SIP, trunking, extensions, dialling and toll fraud specifically, not as an afterthought to a network test.
Right-party authorisation
We take the hosted-PBX authorisation problem seriously and confirm the right party has authorised testing before we begin.
Recurring assurance
Assure repeats the authorised checks on an agreed schedule, human-validated each cycle, so your evidence stays current between assessments, not an always-on monitoring platform.

Credentials & accreditations
We publish accreditations only once they are genuinely held. Where you would expect to see certifications, we would rather show nothing than imply something that is not in place. Ask us directly about our current status for a specific engagement, we will answer plainly.
Find out exactly how exposed your phone system is
Request an authorised PBX, VoIP or SIP security assessment. We confirm scope and authorisation first, then show you what is exposed and what to fix.
Testing is only performed against systems you own or are explicitly authorised to test.
