Cyber threats will intensify for telecom operators in 2026. According to Kaspersky, long-standing risks like advanced persistent threats (APTs), supply chain attacks, and DDoS disruptions will continue, while new technologies are opening up fresh vulnerabilities.
The rollout of AI-driven network automation could backfire if systems act on bad data. Post-quantum cryptography, meant to secure communications, may cause compatibility issues if deployed too quickly.
And with 5G-to-satellite integration expanding coverage, operators face new risks from added points of failure and partner dependencies.
What experts recommend
Kaspersky suggests continuous monitoring of cyber threats, staged automation rollouts with human oversight, and stronger DDoS defenses. They also advise deploying endpoint detection and response tools to spot advanced attacks early and contain them fast.
Telecom operators now face a double challenge: dealing with established cyber threats while preparing for risks tied to AI, quantum security, and satellite integration. Experts say resilience in 2026 will depend on building security into these technologies from the start.
