Fortanix, which provides security by encrypting applications and data at runtime, raises $23M Series B led by Intel Capital
Context & Ripple Effects
This 2019 round is the early step in a funding arc that ran long: three years later Fortanix raised a $90M Series C, taking its total funding to $122M on the same runtime-encryption thesis — protecting data while it is being processed, not just at rest or in transit.
For lead investor Intel Capital, the deal fits a pattern visible across its portfolio: the same firm later led Grip Security's $25M Series A for SaaS data protection, making data-centric application security a repeatable bet rather than a one-off.
First-order effects
- Fortanix gets $23M to scale runtime encryption for enterprise customers, converting an academic-sounding category (data-in-use protection) into a funded product line.
- Intel Capital takes an equity position in a security layer that sits close to the processor — a natural adjacency for a chipmaker's investment arm.
Second-order effects
- Rivals attacking the same workload from other angles — TrueFort's behavior-based app protection, later RapidFort's supply-chain hardening — now compete against a well-funded incumbent defining the 'encrypt everything in use' pitch to the same enterprise security budgets.
- Intel Capital's corporate backing gives Fortanix a credibility signal with hardware-adjacent buyers that pure-play security investors cannot match.
Third-order effects
- If the pattern holds, enterprise security spend migrates from perimeter and at-rest controls toward runtime and in-use protection, with each layer spawning its own venture-funded specialist — Silverfort's identity-threat round shows the same slicing dynamic in adjacent layers.
- Corporate venture arms like Intel Capital increasingly act as kingmakers in security categories, using strategic stakes to align startups with their parent platforms.
The trend: Enterprise security funding is shifting from protecting stored data to protecting data while it runs, with corporate VCs like Intel Capital seeding the specialists in each new layer.
