Safeguarding Telcos and ISPs

Cybersecurity for Telcos and ISPs

Empowering digital transformation, while optimizing efficiency and cost at scale.

In an interconnected world where information is the lifeblood of businesses, Telecommunications (Telco) and Internet Service Provider (ISP) play an indispensable role as the backbone of communication and services. Their infrastructure and services form the foundation for how individuals and organizations connect and communicate, making them attractive targets for threat actors.

Telcos and ISPs are innovating across four key initiatives, spanning networking, internet access, and content delivery that are transforming their industries. And they are aggressively implementing strategic digital transformation programs to support these initiatives to remain competitive, revolutionize the customer experience and expand business opportunities.

Telco and ISP Networks Against Cyber Attacks

Cyber threats loom large, and Telcos and ISPs stand as prime targets for malicious actors armed with advanced and sophisticated tools. Their critical role in facilitating seamless communication and providing uninterrupted internet services makes them attractive prey for cybercriminals. There are many impactful cyberattacks that pose a significant threat to Telcos and ISPs, amplifying the urgency for robust security measures and proactive defense strategies.

Key Cybersecurity Challenges for Telcos and ISPs

Protecting interconnected networks

The Telco industry has vast interconnected networks that cybercriminals can attack.

Securing legacy technology

The Telco industry still uses legacy technology which makes it difficult to maintain and secure their networks.

Keeping sensitive information private

Telco providers store enormous amounts of sensitive data for individuals, businesses, and government agencies.

Increasing threat attack surface

The threat surface increases as the number of services increase and the networks expands.

Lack of awareness

Lack of technical knowledge and awareness within organizations are major challenges to Telco providers and their customers.
