Tigera
Tigera makes Calico, security and networking software for container and Kubernetes environments.
On the record
Checkpoint: FY26 read on Cilium/Cisco bundling pace and whether Tigera Lynx lands named enterprise design partners
The call
Tigera holds real technical ground in Calico but has not raised since 2018 while Cisco pushes Cilium through its enterprise sales machine.
Tigera built Calico, a network security tool used by millions of computer servers worldwide, and many large companies trust it for keeping their systems safe and following rules. Cisco bought its main competitor Isovalent (which makes Cilium) in 2024 and is now selling both products together to big enterprises, which makes it much harder for Tigera to win new customers. Tigera hasn't raised money since 2018 and has stopped hiring, suggesting the company has stopped growing fast. The one thing that could change everything is if Tigera's newer product Lynx wins over major customers faster than Cisco can push them toward Cilium, but most signs point toward Tigera being bought by a larger company rather than becoming independent and thriving.
Why
01
AI pressure: None apparent. AI agents need network policy and identity controls too, and Tigera Lynx is built to govern them, but it just launched and has no proven traction yet. Could AI do the core job? Unlikely.
02
Bigger players: Cisco (via 2024 acquisition of Isovalent/Cilium). Cisco bought the main open-source rival Cilium in 2024 and is bundling it into enterprise sales deals, putting direct pressure on renewals. Could a giant copy it? Yes, easily.
03
What protects it. An 8 million-plus node Calico install base, deep eBPF technical work, and compliance trust that took years for regulated buyers to grant.
What would change this call
Cisco announces Cilium bundled default in new enterprise networking/security suites in FY26. Would show Cisco converting Isovalent acquisition into direct Calico displacement.
Tigera announces a new priced funding round or discloses a strategic review by mid-2027. Would show investor confidence versus prolonged reliance on 2018-era capital.
Tigera Lynx names marquee enterprise design partners within 12 months of its June 2026 GA. Would show real traction as an AI-agent-governance layer, not just a plateaued CNI vendor.

Key numbers
- Calico runs on 8M+ nodes, 100M+ containers
- No new priced funding round since 2018
- Estimated ARR ~$35M, up from $14.4M in 2023
Named risks
- Cisco's bundling of Cilium via Isovalent acquisition erodes Calico's commercial renewal book.
- No priced funding round since 2018 leaves valuation and runway unclear.
- Flat to declining headcount from 2022 to 2024 signals a mature plateau, not hypergrowth.
- Conflicting public data on HQ location and executive leadership indicates weak disclosure discipline.
Rivals, as read in July 2026
| Rival | Direction | Evidence |
|---|---|---|
| Cisco (via Isovalent/Cilium) | losing to | Cisco bought Cilium creator Isovalent in 2024 and bundles it into enterprise sales, gaining new-deployment mindshare by 2026 |
| Aqua Security | contesting | Named as direct container and cloud security competitor per CB Insights, 2026-05-17 |
| Arista Networks | losing to | Arista's ~$2.77B revenue dwarfs Tigera's ~$30M estimate per Growjo, 2022-04-18 |
Questions people ask
- Is Tigera profitable in 2026?
- Tigera has not disclosed profitability. Third-party estimates put annual revenue at roughly 35 million dollars as of November 2024, up from about 14.4 million dollars in December 2023, but no audited financials or profit figures have been published.
- Who owns Tigera?
- Tigera is privately held and venture-backed, with investors including NEA, Insight Partners, Madrona Venture Group, Wing Venture Capital, Samsung Ventures, and Juniper Networks. No new priced funding round has been publicly reported since its Series B closed in December 2018.
- Is Tigera losing to Cisco or Cilium?
- Cisco acquired Cilium creator Isovalent in 2024 and is bundling it into enterprise sales, and industry comparisons as of 2026 note Cilium is gaining mindshare in newer eBPF-native Kubernetes deployments while Calico still leads legacy installs.
- Could AI replace Tigera's product?
- Unlikely soon. Tigera's moat is kernel-level eBPF data-plane engineering and an 8 million plus node Calico installed base with enterprise compliance trust. Tigera is instead using AI itself, shipping Calico AI troubleshooting in November 2025 and Tigera Lynx, an AI-agent governance layer, in June 2026.
- Who is Tigera's CEO?
- Ratan Tipirneni is President and CEO of Tigera, confirmed in a December 7, 2025 interview. One outdated data source lists a different name, but recent 2025-2026 sources consistently name Tipirneni.
- What is Tigera Lynx?
- Tigera Lynx is a unified control plane for discovering, authenticating, authorizing, governing, and auditing Kubernetes-native AI agents. It reached general availability on June 17, 2026, positioning Tigera as security infrastructure for the AI-agent economy.
