Cyber Defense and Cyber Resilience

Anticipate pitfalls and recover quickly

A cyber-attack can be devastating. The actions you take during the first 48 hours can be critical to a successful outcome.

These are complex security incidents requiring specialized skills, tools, and knowledge. The most common scenarios you could face range from an uncertain response to handling security incidents and related outages to unseen threat actors bypassing traditional defenses and detections.

Rigid incident response programs unable to counter dynamic threats and lack of business continuity and/or resiliency strategies, documentation, and response plans are also concerns.

Whether you need help in preparation and planning, retaining direct assistance, or simply need to raise your response readiness profile, Protiviti offers full-service cyber defense and response teams with expertise to match your technology, industry, and situation.

Our cyber defense and cyber resilience approach

Our cyber defense approach is built on three pillars, including:

Crisis management (enabling leaders to achieve their goals in a disrupted environment), implementation without overload (effective and efficient preparation, response, and recovery through a core team), and enabling technical responders (ensuring the most technically skilled people remain engaged in what they do best).
