Appetite for M&A
When August Equity invested in Integrity360 in 2021 (having sold SecureData in 2019 at a 7.2x return), it pledged to “build a substantial leadership position across the European market”.
These weren’t just empty words, judging by the MSSP’s actions in a slowing M&A market last year.
Integrity360 holds the distinction of topping this list despite not making a single UK acquisition last year.
It instead splashed the cash on the international stage in 2025, acquiring sizeable peers in South Africa, France and the Benelux. Its latest purchase – Brussels-based Cresco – boosted headcount to 750 and its number of regional locations across the UK, Europe and Africa to 14.
It is also headquartered in Dublin, not the UK (we opted to turn a blind eye to this because it has a sizeable UK presence thanks to its 2022 Caretower acquisition).
Background bulletin
Fuelled by M&A, Integrity360 has gone from zero to 230 South African employees in less than 18 months.
