Accordingly, security leaders continuously spend money on fresh security tools and platforms to fight an expanding set of new types of cyber attacks such as ransomware, credential-based attacks, and malicious insiders. But not every network security tool plays well with others. More than 75 different security products are used, on average, by the typical enterprise to prevent cyber attacks. This can complicate the landscape and make it hard to deal with. CISOs and other security leaders must streamline their tech stack and concentrate on apps, managed services, and security controls that yield consistent results.
