So much so that, according to a 2020 IBM Institute of Business Value study, more than one in three executives said they experienced data breaches that can be attributed to M&A activity during integration.
Security ratings, provided by security rating services (SRS), can deliver an overview of risk to stakeholders. But attack surface management (ASM) tools give security teams actionable insight on a daily basis throughout the entire M&A process.
To reduce breach risk during what can be an incredibly stressful time, security teams need to understand how SRS and ASM solutions fit M&A challenges.
What are Security Rating Services?
Security Rating Services are designed to measure an organization’s overall cybersecurity risk and provide a security rating score. Sometimes known as cyber risk ratings, these scores are intended to be a data-driven measurement of an organization’s security posture.
SRS can rate risk within a company’s own environment or in a third-party environment. They generally show risk as a number or a letter, similar to a test score. This cyber risk score is calculated based on active and passive data collected by the service provider. Different SRS providers use different algorithms and data inputs to get this score, and there is no standard method or measure of cyber risk scoring.
A typical SRS provider looks at external data sources specific to an organization. Then, it compares those sources to data sets about known cyber risk factors in similar organizations. These ..
