SAN FRANCISCO, Oct. 15, 2025 /PRNewswire/ -- Corelight, the fastest-growing leader in network detection and response (NDR), today announced it has been named a Leader in The Forrester Wave™: Network Analysis and Visibility Solutions, Q4 2025. The report evaluates the 12 most significant providers in the market, assessing them on their current offering, strategy, and customer feedback.

"We see this as an acknowledgement of not just what we do today, but also the growth-driven investment against our vision, innovation, and long-term roadmap, earning us the highest possible score in the vision criterion."

Corelight's Key Strengths Recognized by Forrester

In Corelight's vendor profile, Forrester cited the following:

• Data-Centric Innovation: Forrester noted that Corelight "positions its solution as a network context force multiplier, strengthening attack surface discovery/prioritization and the future SOC." The report states that the company's innovation approach "aligns with a data-centric strategy tailored to its target users" and is "backed by substantial R&D investment."
  
  
• Comprehensive Detection Approach: According to the report, "Corelight minimizes reliance on a single approach to threat detection by relying on multiple mechanisms tailored to specific use cases."

• Proven multi-layered detection strategy – Fusing machine learning (ML), behavioral analytics, curated signatures, and threat intelligence provides defenders with prioritized, aggregated alerts based on risk and expert-tuned detections.
• Open source advantage – Built on an open-source foundation that is used by the world's elite defenders, customers benefit from curated community content contributions that help detect emerging threats faster.
• AI driven acceleration – Integration of large language models and ML-based detection algorithms enables evidence-backed summaries, guided triage, and analyst-ready workflows to accelerate investigations without locking customers into proprietary platforms.
• Flexible deployment options – With a strong and growing technical ecosystem, Corelight Open NDR can be seamlessly deployed in a wide range of architectures from cloud to on-premises to hybrid with integrations across the security stack.
• Leading customer support – An expert team of security professionals provides support and advice to customers from implementation and integration through the entire lifecycle of the customer relationship.
