Protecting telecom networks against the most advanced cyber threats and fraud schemes. Group-IB secures the attack surface from network infrastructure to customer-facing cloud services, keeping services running for subscribers who depend on them.
Telecommunications providers have one of the most complex attack surfaces, covering high-volume networks, sensitive subscriber data, customer-facing applications, and distributed infrastructure. Group-IB telecom cybersecurity solutions help organizations reduce breach exposure and detect advanced threats with intelligence-led technologies and expert services.
Subscriber fraud is one of the most damaging operational risks in telecom. Attackers use SIM swap to hijack numbers and intercept one-time passwords, exploit weak authentication on SIP trunking services to spoof caller IDs, and combine voice phishing with social engineering to drain accounts. Decreased customer trust results in higher turnover, and regulators are enforcing stricter rules on caller ID authentication to protect subscribers.

Group-IB Fraud Protection uses behavioral biometrics, device fingerprinting, and explainable AI to detect SIM swap, voice fraud, and account takeover attempts as they happen, before transactions complete. Risk signals are shared across telcos and banks to catch coordinated fraud rings early, which means fewer successful takeovers and less friction for legitimate customers.
When fraud or breach activity escalates beyond automated controls, Group-IB Incident Response contains the threat, identifies the entry point, and reconstructs the attacker’s full kill chain. The team then closes the gaps that enabled the initial compromise, so the same actors cannot return. Operations resume faster, and exposure is reduced before regulators or customers learn of the incident.

Use Group-IB Threat Intelligence to track ransomware strains, data breaches, exploited vulnerabilities, and threat actor activity targeting the telecom industry. Tailored intelligence helps organizations understand attacker tactics, prioritize defenses, and identify high-risk methods before they reach your network.

Gain comprehensive oversight of your organization’s digital footprint, including online brand presence, social media, and digital assets. Group-IB Digital Risk Protection monitors for impersonation attempts, phishing campaigns, and other forms of digital fraud that could target your customers.

Telecom operators possess a large amount of personal data that is stored across various systems, which makes it susceptible to security breaches. If an attacker gains access to one system, they may be able to reach others, creating multiple pathways for data exfiltration. Data breaches can lead to legal obligations under GDPR and sector-specific regulations, as well as incident reporting requirements and an increase in class-action lawsuits. Tight disclosure timelines mean that a single breach can potentially expose millions of customer records at once.

Group-IB Managed XDR provides 24/7 detection of exfiltration patterns and unauthorized data movement across endpoints, network, and cloud workloads in real time. Our analysts investigate anomalies before they become breaches, with full attack-chain context to support reporting if disclosure is required. Sensitive customer data stays inside your organization, and the incident response timeline drops from weeks to hours.

Reduce the risk of breaches originating from email, the primary attack vector for cybercriminals and nation-state actors targeting telecom networks. Opt for the solution that also uses encryption to protect sensitive information for any number of enterprise employees.

Having an incident response retainer means having a dedicated team ready to jump into action when an attack is detected, ensuring a swift and effective response to mitigate damage and recover data. Group-IB Incident Response Retainer comprises a rapid SLA which is the best proactive solution that saves your time, money, and reputation.
Group-IB Threat Intelligence monitors dark web markets and leak sites for compromised credentials and exposed databases involving your organization or suppliers. Early warning gives security teams time to contain exposure and notify affected subscribers before attackers can act on stolen data. This also allows you to brief regulators and notify subscribers before the breach is leaked publicly.

Group-IB Cloud Security Posture Management audits your environment to identify misconfigurations that could lead to data leaks. The solution detects issues such as publicly exposed storage buckets, overly permissive access on customer databases, and gaps in identity and encryption across AWS, Azure, Google Cloud Platform (GCP), and hybrid setups. It provides actionable remediation guidance, allowing security teams to address issues efficiently while keeping subscriber data secure as workloads grow.

SOCs struggle with understanding threats, such as identifying IP addresses, malware families, or system owners. Addressing this involves setting up a threat intelligence program, using asset management solutions, conducting system owner interviews, and applying vulnerability and attack surface management tools to gain a comprehensive threat perspective.

This process not only identifies vulnerabilities but also correlates them with potential external threats. Understanding these vulnerabilities in context allows your SOC to prioritize the highest-risk exposures and strengthen defenses where it matters most.

SOCs face staff shortages in roles like SOC managers, incident responders, and analysts. Addressing this requires regular training and education. Consulting services help in building SOC capabilities from scratch, focusing on personnel coaching, supported by process documentation and interactive workshops to enhance team competency.

ISC2 (2025) found that most cybersecurity professionals lack specialist skills in AI, cloud, risk, and application security.
This investment in knowledge ensures that all team members are equipped with the necessary tools and understanding to handle cyber threats and maintain the security of complex telecom networks. Group-IB programs cover everything from basic cybersecurity awareness to advanced technical skills, equipping staff and maintaining telecom network security.

Exercises simulate real-world attacks, challenging and testing the SOC team’s response capabilities. This hands-on approach helps in identifying potential security gaps, improving threat detection and response strategies and foster a deeper understanding of attacker tactics, techniques, and procedures (TTPs).

SOC consulting provides invaluable support to telecom companies facing skill gaps in their security teams. They assist in developing and refining processes, and in training existing staff, thereby improving overall SOC efficiency. This approach not only enhances current capabilities but also prepares the SOC to face future challenges.

Expanding attack surfaces, including cloud infrastructure and VPNs, challenge enterprise-wide visibility. Addressing this involves using attack surface management for external assets and establishing a vulnerability management service for internal assets, complemented by regular OSINT drills to understand public exposure and deter adversaries.
