Improving Cyber Security Reading by Achieving Maturity Across CIS Top 20 Controls
The Client

The executive team of a leading technology and services company was looking to secure its assets from any possible cyber-attacks. The employees would work on various projects for the customers and had a range of assets like laptops, servers, USBs, smartphones, and other devices. The employees would work from different locations, and managing and maintaining security standards was complex. 

Rather than debating what security standards best fit the situation, the leadership decided to go with CIS controls and approached us to help execute. CIS Top20 Controls helped the client achieve the required security standards quickly and saved the time of starting from scratch. 

The Challenge
Inconsistent Risk Management

The client evaluated multiple vendors before selecting us for the project. However, vendor assessment and evaluation took too much time and effort. With the lack of automation in the collection and analysis of vendor surveys, the process was cumbersome and manual. But ultimately, we were selected for CIS Top 20project for the client because of our long-standing relationship and approach to the overhaul of security standards.

One of the biggest challenges at hand was centralizing third-Party risk management functions. The customer worked with multiple vendors and third-party service providers and was looking to extend the CIS standards to those relationships and transactions. One of the goals of this entire exercise was minimizing inconsistent vendor risk management methodologies.

The Solution

By implementing the CIS Top 20 Controls, we helped strengthen our client’s security posture, earning their trust and reinforcing their market reputation.This industry-recognized framework was essential in establishing robust cybersecurity practices. CIS hardening played a key role in safeguarding the client’s environment against both internal vulnerabilities and external threats, ensuring compliance and resilience.
