IT Security Consulting Services Market Growth Trends Reshaping The Competitive Landscape
Leading companies in the IT security consulting service market are developing innovative offerings, such as assessment applications, to better cater to customers with enhanced features. An assessment application serves as a software tool or platform crafted to aid in the evaluation, measurement, or analysis of various benchmarks, like skills, knowledge, performance, or proficiency. For example, in December 2023, NRI SecureTechnologies Ltd., an IT service management company from Japan, introduced a security assessment service called AI Red Team, which is dedicated to evaluating systems and services by employing generative AI. As part of this service, NRI Secure’s specialists carry out simulated attacks on operational systems to gauge AI-specific vulnerabilities in LLM (Large Language Models)-based services and uncover issues within the broader system, including functions peripheral to AI, thereby delivering an all-encompassing evaluation. This service utilizes a two-stage assessment approach, initially addressing risks contained within the LLM itself, followed by an appraisal of the complete system incorporating the LLM. The outcomes of the assessment are compiled into a comprehensive report that details the identified problems and recommends mitigation strategies.
