Telecom cybersecurity, where the attack converts straight into a bill

Telecom has a threat the rest of the industry does not: fraud that turns compromised access directly into billable traffic, often overnight, often over a weekend.

What changes here

Cybersecurity Services in telecommunications is not the same engagement

Toll fraud defence that works at 3am on a Saturday

Rate limiting, destination controls, and anomaly alerting tuned so that a compromised SIP credential is contained in minutes rather than discovered on the interconnect invoice.

Signalling abuse tested, not assumed

SIP registration, authentication, and topology testing against the techniques used in the wild, including enumeration and registration hijacking.

Subscriber data treated as its own class

Call detail records, location, and account data carry specific obligations. Access to them is designed and evidenced separately from general system access.

What the regime actually requires

Operators carry obligations over subscriber information and call authentication that most other sectors do not, with the FCC and CRTC both active in the area.

Talk it through
  • Customer proprietary network information protected and access-controlled under FCC CPNI rules
  • Annual CPNI compliance certification for carriers subject to it
  • STIR/SHAKEN call authentication posture for IP-originated traffic
  • Robocall mitigation obligations, with the associated database filings kept current

The work itself

Full cybersecurity services page

Penetration testing and application security

Authenticated testing of web, mobile, and API surfaces against the OWASP Top 10 and business-logic abuse, with reproductions rather than scanner output.

Cloud and infrastructure security assessment

IAM, network exposure, storage, encryption, and logging reviewed against CIS benchmarks across AWS, Azure, and Google Cloud.

Code and supply-chain review

Secure code review on the paths that handle money, identity, and personal data, plus dependency, image, and secret scanning wired into CI.

Remediation alongside your engineers

We fix, or pair with the people who will — prioritized by exploitability and blast radius, then retested so the finding is closed rather than acknowledged.

SOC 2, HIPAA, and PCI DSS readiness

Control mapping, policy and evidence collection, and the technical gaps closed before an auditor names them. We prepare you; the audit itself is signed by a licensed firm.

Monitoring, response, and access review

Security logging that survives an incident, an incident-response runbook rehearsed once rather than never, and access reviews on a schedule.

Telecommunications questions we get asked

Something more specific? Send us the situation and we’ll answer it straight.

Layered: strong credentials and registration controls, destination and rate limits per account, and anomaly detection with automatic containment. The key metric is time to contain, since fraud runs fastest exactly when nobody is watching.
Customer proprietary network information — who your subscribers called, when, from where, and what services they buy. It applies to telecommunications carriers and interconnected VoIP providers, and it carries specific access-control, training, and annual certification obligations.
It is call authentication rather than security in the classic sense, but the two meet in practice: attestation levels affect delivery and reputation, and a compromised account originating spoofed traffic damages both. We review the posture alongside the fraud controls.
With filtering at the network edge, because these protocols were designed for a trusted operator community that no longer exists. A signalling firewall that validates messages against what a legitimate roaming partner would send blocks the location-tracking and interception categories, and the work is largely in tuning it without breaking real roaming.
You are into breach notification obligations quickly, and in the United States CPNI carries its own reporting path in addition to state law. The engineering consequence is that you need to establish what was accessed rather than what could have been — which depends entirely on logging decisions made long before the incident.
Management interfaces off the routable network, jump hosts with recorded sessions, named accounts rather than shared vendor logins, and multi-factor enforced at the boundary. Vendor support access is the specific worth auditing first: standing accounts with permanent credentials are common and rarely reviewed after the installation they were created for.
