End-to-end encryption protects Signal in transit. Messages, calls and attachments are captured on the endpoint, after Signal decrypts them for the user.

Signal's strong privacy reputation is precisely what makes employees willing to send sensitive files through it — and what makes it a blind spot for security teams.
End-to-end encryption means every message and call is unreadable on the wire. Perimeter firewalls, proxy inspection, and network DLP tools see only encrypted noise — the content is gone before it ever reaches them.
Anexet takes a different approach: it captures Signal on the endpoint, after the Signal Desktop app has already decrypted the content for the user. Coverage runs across Windows, Linux, and macOS workstations, so the encryption barrier no longer applies. Calls are saved as audio, and interception can be filtered down to a specific phone number.
Network and proxy inspection see only ciphertext — only endpoint capture actually reads the content.
Signal's privacy reputation encourages employees to share files, calls, and discussions they would avoid in other channels.
Signal calls carry conversations that never touch a chat log — Anexet saves them as audio, tied to the same user record as messages and files.
Everything you need to bring Signal on managed endpoints under control, in a single lightweight agent.
See who uses Signal Desktop, when, and how often. Usage time and activity feed straight into employee-monitoring and productivity reports.
Capture messages, calls, and shared attachments on the endpoint — searchable in the Client Console with the user identity and timestamp behind every event. Calls are stored as audio, and interception can be narrowed to a specific phone number.
Security policies stop risky message and file transfers, and content-aware rules match by digital fingerprint, keyword, or sensitivity label — so confidential data stays off Signal.
Anexet records Signal activity as the user sees and hears it: individual conversations, calls saved as audio, and shared attachments — with the user identity and timestamp attached to every event. Capture happens on the endpoint, so Signal's end-to-end encryption does not prevent it.
Because capture runs on the workstation rather than the wire, no network decryption is needed. The Signal Desktop client is covered on Windows, Linux, and macOS workstations, and interception can be filtered by phone number. Security policies can block file and message transfers in real time, and content-aware rules go further — matching a digital fingerprint, keyword, or sensitivity label before a document ever leaves.
From a Signal message on the endpoint to a controlled, searchable record.
A lightweight agent on the workstation captures Signal Desktop activity — on Windows, Linux, and macOS alike — after the app decrypts content for the user.
1
Captured messages, calls, and attachments are sent to your on-premise server and indexed for search; calls are stored as audio and interception can be filtered by phone number.
2
Security policies scan content in real time and can block, quarantine, or alert on a match.
3
Analysts review conversations, build cases, and export court-grade evidence from the Client Console.

Common questions about how Anexet handles Signal.
Yes. Anexet captures Signal on the endpoint — after the Signal Desktop app has already decrypted the message for the user — so encryption on the network does not prevent monitoring. Messages, calls, and attachments are captured as the user sees and hears them.
Anexet covers the Signal Desktop client the same way on Windows, Linux, and macOS managed workstations, capturing messages, calls, and files across all three.
Both. Signal calls are saved as audio, tied to the same user identity and timestamp as messages and attachments, so a voice conversation is on record just like a chat.
Yes. Signal interception can be filtered by phone number, so you can scope monitoring to specific accounts rather than capturing every conversation across the workstation.
Yes. Security policies can block message and file transfers, and content-aware rules match by digital fingerprint, keyword, or sensitivity label — so a confidential document can be read in the console but never sent. Exact rule options for your environment are confirmed during the demo.
Anexet is deployed on-premise; the vendor has no access to your data. All captured Signal content stays inside your own infrastructure.
Anexet covers Signal Desktop on managed Windows, Linux, and macOS workstations. Anexet does not run mobile agents, so iOS and Android Signal apps sit outside that coverage.
Signal tracking and interception come with the Standard plan. Advanced adds blocking policies and content-aware rules for Signal file and message transfers, and Premium extends that with the full analytics and investigation toolset. The exact fit for your Signal monitoring needs is confirmed during the demo — pricing is always individual.
Never. Anexet is fully on-premise: all captured data is stored on your own servers, and the vendor has no access to it at any point.
