ESG Technical Review: Managing Risk, Complexity, and Cost with SanerNow Endpoint Security and Management Platform

The Challenges

As organizations of all sizes embrace digital transformation and the shift to modern cloud architectures, their IT infrastructure is both growing and becoming more complex. Indeed, two-thirds (68%) of respondents to an ESG research survey said that their IT environment had become more complex in the last two years.1

Complex infrastructures have large attack surface areas, necessitating a variety of cybersecurity tools and techniques to protect them against ever-increasing volumes and sophistication of attacks. However, cybersecurity teams report numerous challenges managing an assortment of security products from different vendors, such as the inefficiencies created by having separate management and operations for each tool, cited by 27% of ESG research respondents as a challenge, or different tools for various parts of the IT infrastructure (24%), or the number of security tools making operations complex and time consuming (22%)
