Proofpoint and Littlefish Announce Strategic Acquisitions
Tech services M&A activity continues with two notable deals. Proofpoint acquired AI security firm Acuvity to secure the "agentic workspace," referring to human-AI collaboration environments. In a separate deal, managed services provider Littlefish Group purchased cybersecurity specialist Stripe OLT to bolster its end-to-end Microsoft services.
- The acquisition of Acuvity brings technology designed to monitor and secure AI systems that handle sensitive business functions, addressing risks like "shadow AI," data exposure, and new attack types such as prompt injection. - Acuvity, a 2023 startup, had previously raised a $9 million seed funding round in September 2024 to develop its platform for providing visibility and language-based access controls for generative AI. - Proofpoint has a history of strategic acquisitions to bolster its security offerings, including the $225 million purchase of insider threat management firm ObserveIT in 2019 and a reported over $1 billion deal for Hornetsecurity in 2025. - The Littlefish acquisition of Stripe OLT creates a combined workforce of 900 specialists and is aimed at accelerating the expansion of its managed services and advanced cybersecurity operations across the UK. - Stripe OLT enhances Littlefish's portfolio with a CREST-accredited Security Operations Centre (SOC), along with expertise in threat detection and offensive penetration testing. - This deal strengthens Littlefish's ability to serve organizations with complex regulatory and security needs, building on its client base in the public sector and national healthcare services. - The move follows Littlefish's August 2024 acquisition of Irish Microsoft consultancy Storm Technology, indicating a consistent strategy of expanding its Microsoft-focused service capabilities through M&A. - These acquisitions align with a broader market trend of increased M&A activity in the cybersecurity sector in 2024, which saw a 13.6% year-over-year rise in transaction volume, driven by the integration of AI and a rising number of cyberattacks.
