“Understanding the evolving landscape of cyber threats is crucial for any organization striving to safeguard its assets and processes. Our findings reveal that the resilience of cybercriminals grows as technology advances, pushing organizations to not only respond but also to anticipate and adapt their security measures proactively,” comments Konstantin Sapronov, Head of Global Emergency Response Team at Kaspersky.
To strengthen your company’s protection against sophisticated attacks, deploy robust cybersecurity solutions and hire qualified practitioners to manage them or adopt managed security services such as Managed Detection and Response and Incident Response. These security services encompass the complete incident management cycle from threat identification to continuous protection and remediation. They assist in safeguarding against evasive cyberattacks, investigating incidents and offering expert support even if a company lacks security workers.
