Claroty named OT security leader

Claroty said on September 1 that Forrester Research named it a Leader and a Customer Favorite in “The Forrester Wave: Operational Technology Security Solutions, Q3 2026.” The ranking put fresh attention on a market focused on securing industrial control systems, connected devices and other operational networks. A day earlier, Jack Henry disclosed a cybersecurity incident in a limited portion of its internal, non-production corporate environment. (prnewswire.com) Taken together, the two announcements show how vendor rankings and live incident response are unfolding at the same time across cyber-physical and enterprise environments. (forrester.com) ### What exactly did Forrester say about Claroty? Forrester published its Q3 2026 operational-technology security report on September 1 and said it evaluated 11 providers in the category. (prnewswire.com) Claroty said the report named it a Leader and a Customer Favorite, and the company said it received the highest possible score in nine criteria. Claroty, which describes itself as a cyber-physical systems protection company, said the evaluation covered current offering and strategy. Its website now highlights the Forrester designation alongside earlier market-recognition claims tied to cyber-physical systems protection. ### What does “OT security” cover in practice? Operational technology security refers to systems that run physical processes — factory equipment, industrial controls, building systems, medical devices, utilities infrastructure and other connected assets that sit outside standard office IT. (prnewswire.com) Forrester’s report description says it is meant to help buyers compare significant operational-technology security providers and select products for those environments. (forrester.com) Claroty uses broader “XIoT” and cyber-physical systems language for that same problem set. The company says its platform is built to secure cyber-physical systems across operational environments where downtime and asset visibility are central concerns.

Jack Henry said on August 31 that it had detected a cybersecurity incident within a limited portion of its internal, non-production corporate environment. The financial-technology company said no client-facing systems, operating systems, core platforms or daily processing services were accessed or disrupted, and it said it did not experience any system outages. Monett, Missouri-based Jack Henry said it activated its incident-response protocols, contained the issue and engaged third-party cybersecurity experts. (forrester.com) The company also said it notified law enforcement and was continuing its investigation. (claroty.com) ### Why put these two developments side by side? September 1 and August 31 produced two different kinds of cybersecurity signal. One was a market-ranking announcement from Claroty tied to OT security buying criteria; the other was an incident disclosure from Jack Henry describing containment steps and operational status after a breach in a non-production environment. (prnewswire.com) Forrester framed its report as a buyer guide for operational-technology security solutions, while Jack Henry’s statement focused on business continuity and investigation. The overlap is that both documents center on resilience: one through vendor evaluation, the other through incident handling and system segregation. That reading is an inference from the two disclosures. (prnewswire.com) ### What should readers watch next? Jack Henry said its investigation was ongoing as of August 31, with outside cybersecurity specialists and law enforcement involved. Any next public update is likely to come through its investor-relations site or a new company statement. (prnewswire.com) Forrester’s Q3 2026 report is available through Forrester, and Claroty is using the result in its current market materials. The next concrete milestone on this story is whether Jack Henry discloses additional findings or remediation steps as that investigation continues. (ir.jackhenry.com) (forrester.com)
