Cisco acquires cloud-native security and networking startup Isovalent, which had raised $69M and has helped develop open-source projects eBPF and Cilium
Context & Ripple Effects
Isovalent emerged around Cilium as a cloud-native networking and security service after its 2020 debut from stealth, then raised a $40M Series B to continue building the open-source software. The acquisition moves that specialist capability into Cisco after Isovalent had raised $69M overall.
Cisco had already bought Kubernetes-security startup PortShift, making its earlier Kubernetes-native security acquisition a relevant precursor. Subsequent coverage put the Isovalent deal at roughly $650M in cash, underscoring the value assigned to its cloud-native security position.
First-order effects
- Cisco gains Isovalent’s cloud-native networking and security team and its commercial position around Cilium, while Isovalent transitions from an independent vendor to a Cisco-owned business.
- Cilium users and contributors gain a much larger corporate backer, but its stewardship is now more closely tied to Cisco’s product and platform priorities.
Second-order effects
- The deal strengthens Cisco’s ability to pair Kubernetes-native security with networking, increasing pressure on standalone cloud-native security vendors to differentiate through neutrality, broader ecosystems, or deeper specialization.
- Enterprise buyers evaluating Cilium-based deployments may weigh Cisco’s support and integration capacity against the trade-off of relying on a vendor-owned open-source ecosystem.
Third-order effects
- If large infrastructure vendors continue acquiring open-source cloud-security specialists, independent projects can become key control points in broader networking and security stacks rather than standalone commercial markets.
- The pattern highlights specialist absorption risk: open-source adoption can create strategic value for a project while concentrating its commercial stewardship inside incumbent vendors.
The trend: Cloud-native networking and security are becoming strategic acquisition targets as incumbents seek control of the open-source layers used in Kubernetes environments.
