Colchix vs. NordLayer

Network security from Nord Security, with a managed browser that controls what can be pasted or uploaded. Strong where it stands. Under the X-ray, here's where it breaks, and what Colchix brings instead.

  1. Can't tell an IBAN from a recipe
  2. Block it, or allow it all
  3. Only covers its own browser
  4. Never reads the text

The benches

NordLayer's ship, and ours

Governing AI takes a whole crew: the console, the lookout, the guard, the scribe and the judge.

NordLayer

  • One consoleThe ship

    Half done.

    A network console; AI is one more site

  • ARGUSThe lookout

    Half done.

Colchix

  • Colchix OSThe ship

    Filled.

    One console for every AI tool and every team, with the gap still to cover given as a number.

  • ARGUSThe lookout

    Filled.

    Finds every AI tool on every device, personal accounts included, without reading a prompt.

  • TALOSThe guard

    Filled.

    Masks the secret, keeps the question, and puts the real values back while the answer streams.

  • ATHENAThe scribe

    Filled.

    Turns everyday AI activity into evidence for the EU AI Act, GDPR and ISO/IEC 42001.

  • THEMISThe judge

    Filled.

    Our own model, in Europe: finds and judges in one pass, a confidence for every value, under 100 ms (target).

Head to head

NordLayer and Colchix, row by row

How values are foundNordLayer: It doesn't read the textColchix: THEMIS finds and judges in one pass over the whole textA separate finder caps what can be protected: regex alone found 59 in 100, a finder then a judge 69.
Exact boundariesNordLayer: Not applicableColchix: Trained and scored on exact spans (target: ≥ 90 in 100 protected)Half a value leaks: mask “Kestrel” in “Project Kestrel” and the project is still named.
Would masking break the request?NordLayer: NoColchix: Asked for every value, and learned from examplesMask everything and the answer is useless; mask nothing and it leaks.
Confidence per valueNordLayer: Not applicableColchix: A calibrated probability for every valueA threshold on an uncalibrated score is a guess.
Real values back in the replyNordLayer: Not applicable: it blocks or allowsColchix: Yes, restored while the answer streamsAnna gets a usable answer instead of [REDACTED].
Whole attachmentsNordLayer: Blocks the uploadColchix: 16k tokens in 0.8 s (target); refuses rather than cutsPeople attach contracts and exports. A silent cut-off is a silent leak.
Speed on every sendNordLayer: Not applicableColchix: Under 100 ms per message, median (target)It sits in front of the send button. Slow protection gets switched off.
Where the model runsNordLayer: No modelColchix: Our own weights, in the EU, or in your own cloudResidency, and no new sub-processor for your DPO to object to.
Evidence for auditsNordLayer: No AI evidence documentedColchix: ATHENA files every record under the rule it provesThe EU AI Act, GDPR and ISO/IEC 42001 ask for proof, not policies.
Every AI tool, every deviceNordLayer: Its own browser onlyColchix: ARGUS finds them all, personal accounts includedYou can't protect what you can't see.

The same prompt

Only one answer comes back whole

Anna asks for a reminder about a late invoice, with an email and an IBAN in it.

Anna, accounts payable types

The only choices: ChatGPT with everything in it, or ChatGPT without paste.

Anna read

Dear jane@acme.com, invoice IT60X0542811101000000123456 is now 14 days late…

The provider never saw the email or the IBAN.

Colchix vs. NordLayer FAQs

What people ask when they put Colchix next to NordLayer.

What's the difference between Colchix and NordLayer?

NordLayer controls actions on sites: it can stop a paste or an upload into ChatGPT, but it never reads what's being sent. Colchix reads it, masks only what's sensitive and gives the real values back in the answer, so people keep using AI instead of working around a block.

Isn't blocking safer?

Blocking moves the risk elsewhere: people paste into a personal account or a tool nobody approved. Colchix keeps the useful path open and protects what passes through it, and ARGUS shows the tools people turn to.

Do people have to switch browser?

No. Colchix works in the browsers and AI apps people already use, through a light extension and desktop agent.
