Data-leak prevention for encrypted traffic

Encryption hides the attackers. It also hides your leaks.

Bitsupervisor detects and stops sensitive information leaving your network inside encrypted traffic — web, messaging, files and live voice. No endpoint agents. Nothing ever leaves your premises.

Case files

None of these were hacks. They were information flows.

From battlefields to boardrooms, the most damaging leaks used approved, often encrypted channels. Open a file, then replay it with Bitsupervisor inline.

The Taurus call

INTERCEPTED

Russia recorded 38 minutes of Germany's air-force chief and three officers discussing Taurus missiles for Ukraine on a Webex call. One participant had joined from a hotel in Singapore. Russian state media published the recording on 1 March 2024.

Replays are an illustrative mapping of Bitsupervisor policies onto publicly reported facts.

The shift

Stop chasing attackers.
Watch the information.

Attackers change every day, and insiders are not attackers at all. The constant is the secret itself: the drawing, the source code, the spoken sentence. Bitsupervisor recognises it in any flow — whoever moves it.

How it works

One inline sensor. Every channel. Nothing leaves your site.

STEP 1 · DECRYPT

Open encrypted traffic locally

TLS is terminated on your own hardware, never routed through a vendor cloud.

STEP 2 · INSPECT

Recognise your secrets

Defined secrets, watermarks and labels — in text, files, binaries and live audio.

STEP 3 · DECIDE

Apply your policy

Allow, redact, block or alert, with responses you can program in Python.

STEP 4 · RE-ENCRYPT

Clean traffic flows on

Users notice nothing — until something sensitive tries to leave.

    Coverage

    Classic DLP guards the front door. We watch the windows.

    Calls, messengers, DNS tunnels, personal cloud and AI chatbots are where information leaves today — often from devices that never get an agent.

    Web & SaaS

    Uploads, forms and webmail over HTTPS

    Email

    Bodies and attachments on encrypted transport

    Messaging

    Teams chat and other collaboration tools

    Live voice

    Teams, Zoom and Webex audio, risk-scored in real time

    DNS & UDP

    Tunnels and covert channels that malware loves

    Files & binaries

    Documents, source code and executables

    GenAI prompts

    Code and secrets pasted into chatbots

    Images & video

    Screenshots, photographed drawings, clips

    Who we protect

    Built for organisations where a leak is existential.

    Defence & dual-use

    Classified programmes

    Export-controlled and classified data, on networks that cannot route traffic through a vendor cloud.

    High-tech manufacturing

    Designs & know-how

    CAD drawings, firmware, source code and process recipes — the targets of economic espionage.

    Government & research

    State & research secrets

    Ministries, agencies, institutes and universities with sensitive, unpublished work.

    Critical infrastructure

    FAQ

    Questions security teams ask.

    Does our data go to your servers?

    No. All analysis runs on your premises, and air-gapped sites are supported. Your data stays under your control at all times.

    Do we need to install agents on every device?

    No. One inline gateway covers laptops, phones, servers and IoT on your network, regardless of operating system.

    We already encrypt everything. Why do we need this?

    Encryption protects data from outsiders. It does not stop insiders, honest mistakes or malware that already has legitimate access — and it hides those leaks from your other tools.

    How does it affect network performance?

    Analysis is stream-based to keep added latency minimal. Capacity is sized for each site during the Proof of Value.

    What about employee privacy and works councils?

    Policies target defined secrets, not people. Roles, logging and retention are configurable to support GDPR and co-determination requirements.

    Live demo

    Watch a secret get stopped inside encrypted traffic — in five minutes.

    We show Bitsupervisor on live traffic: a file blocked in an HTTPS upload, code redacted from a chatbot prompt, a risky call flagged in real time. Then we scope a Proof of Value on your network.
