Comprehensive protection of telecommunications against general and specific threats

Money is the lifeblood of the economy, and telecommunications is its nervous system. Complex infrastructure and huge volumes of confidential data increase the risks for telecom providers. However, not only are ISPs susceptible to telecom attacks, but also enterprises using digital telephone services are.

With extensive experience in telecommunications security, H-X experts provide a full range of corporate IT security services: from audit and security assessment of communication systems to Security Operations Center services (SOC-as-a-Service), taking into account the specifics of the telecom industry. Find out more about our security services for telecommunications and discuss your security challenges with us.

Protection of voice telecommunications Assess the security of your telecommunications with VoIP auditing. Protect your telecom services from TDoS attacks and Caller ID spoofing by filtering calls, securing IVR systems, and implementing a resilient telecom platform.

Penetration testing Test the resilience of your IT systems, staff, or organization as a whole using ethical hacking techniques. We assess the likelihood and potential paths of unauthorized access, service disruption, and other security incidents.

DDoS Protection and Performance Testing Prevent business downtime, reputational damage, and financial losses with our comprehensive approach to DoS/DDoS protection at base and application levels, as well as effective “live” testing at all levels.

Security compliance audit Gain a market advantage by aligning your organization with international security standards, regulatory requirements, and frameworks such as ISO 27001, SOC 2, NIS 2, PCI DSS, GDPR, HIPAA, IEC 62443, the AI Act, MiCA, and others.

Incident investigation and forensics Determine who compromised your systems, when it happened, and how the attack was carried out. We carry out detailed research including media analysis and apply cutting-edge techniques such as RAM, registry, shadow volume analysis, timeline analysis, and more.

Telecom providers and vendors build, manage, and maintain complex network infrastructure, which is used for data transfer. Their solutions transmit and store huge volumes of sensitive data that have always been a great lure for attackers. All this makes telecom solutions the target of numerous cyber attacks.

It was telephone systems that became the first targets of hackers. It would seem that the telecom industry should have had time to defend itself. However, due to the increasing complexity of telecommunications technologies, new vulnerabilities continue to emerge.

According to PwC Global State of Information Security, IT security incidents in the telecommunications sector have grown by 45% over the last year. Communication providers are facing a difficult task: they now need to learn how to defend against various cyber threats:

SS7 and Diameter Signaling Threats
SIP Hacking
DNS Attacks
Network Attacks on IoT
DDoS and TDoS Attacks
Targeted Attacks
Unaddressed Software Vulnerabilities
Service Misconfiguration
Other threats

Vendors and corporate communication providers need to consider security as an ongoing process that includes predicting threats as well as preventing, detecting, responding, and investigating them.
