Quantum-safe encryption for the network you already run.
Tessera adds a post-quantum layer inside your existing tunnels. No rip-and-replace. No vendor in your trust path.
Two problems with current network encryption.
Quantum computers will break today's public-key cryptography
The key exchanges that protect IPsec and TLS today rely on mathematical problems a quantum computer solves efficiently. This is established theory, not speculation, and it is why NIST finalised replacement standards (FIPS 203, 204 and 205) in August 2024. The open question is the date, not the outcome.
Your traffic is being recorded now for decryption later
Recording ciphertext requires no breach of your network, only a copy of traffic in transit. Data whose sensitivity outlives the quantum timeline, such as SCADA topologies, patient records and defense communications, is therefore already exposed. The defence is to make today's recordings worthless before they become readable.
The regulatory clock.
CNSA 2.0: PQC in network equipment by 2026, exclusive use by 2030.
ENISA transition guidance; critical-infrastructure deadline 2027.
NCS 2:2025 mandates quantum-safe security across critical national infrastructure.
ANSSI stops certifying non-PQ products in 2027; quantum-safe-only procurement by 2030.
One added component. Your network untouched.
Tessera wraps a post-quantum layer inside your existing tunnel. The edge routing device still routes, the Guard only encrypts, and the Distributor only introduces peers. The diagram below plays the whole sequence: session establishment for the first packet, then steady state, where traffic flows directly and the Distributor is out of the loop.
Comparison with existing approaches.
| What you want | What others give you | What Tessera gives you |
|---|---|---|
| Your secrets stay secret, from everyone | ✕ "Trust us, we manage your keys safely." | ✓ Built so we cannot read your traffic, even if we are hacked. Keys live only inside your own two devices. |
| Deploy without breaking anything | ✕ Replace boxes, re-address networks, schedule outages. | ✓ Drops in beside your network and adds protection underneath. Everything keeps running as it does today. |
| Know the other end is who it claims | ✕ Checked once, at install. | ✓ Every device constantly re-proves it is untampered, and a compromised one is cut off at once. |
| Keep running during a vendor outage | ✕ If their cloud goes down, you are exposed. | ✓ Your protected links keep running through our outages. You never depend on us being online. |
| Connect to other organizations safely | ✕ Not offered, or you trust a shared middleman. | ✓ Organizations connect through us precisely because we cannot read either side. |
| Stay in control of your country's security | ✕ A foreign-government-licensed trust root. | ✓ A sovereign option with no foreign trust root, and a top tier that runs entirely on your premises. |
