IoT security company ForeScout Technologies acquires Netherlands-based industrial security company SecurityMatters for $113M

Context & Ripple Effects
ForeScout is buying its way into industrial networks just over a year after it priced its IPO at $22/share — a listing that valued the company below its 2016 private mark, leaving it under pressure to show a growth story beyond enterprise IoT device visibility. SecurityMatters gives it Netherlands-based industrial threat detection, the operational-technology side of the market where attacks hit physical infrastructure.
The deal sits inside a broader consolidation wave among mid-size security vendors: F-Secure bought MWR InfoSecurity for roughly $106M earlier in 2018, and Proofpoint followed in 2019 with its $225M ObserveIT purchase — established vendors paying nine-figure sums for specialist detection capabilities instead of building them.
First-order effects
- ForeScout immediately adds industrial-network monitoring to its device-visibility platform and gains a European engineering base, while SecurityMatters' product and team fold into a publicly listed buyer with distribution they lacked alone.
Second-order effects
- Rival IoT and endpoint security vendors now face the same capability gap in OT detection, and the comparable deals — Proofpoint's $225M ObserveIT acquisition, F-Secure's MWR buy — signal rising prices for the remaining independent industrial-security specialists.
Third-order effects
- If the pattern holds, standalone OT and industrial-security firms get absorbed into broader platforms spanning IT and operational networks, thinning the field of independent specialists.
- ForeScout's own trajectory frames the structural question: a sub-$1B IPO followed by this acquisition and then the $1.9B Advent International take-private suggests public markets consistently priced these security platforms below what strategic and private-equity buyers thought they were worth.
The trend: Cybersecurity vendors are consolidating specialist detection capabilities through serial nine-figure acquisitions, with industrial and OT security the most contested frontier.
