Telegram CRM security: sessions, encryption and dedicated proxies

To run your account, Entergram has to hold your Telegram session. It is encrypted with AES-256-GCM, your message history is not kept in our database, and every account reaches Telegram through its own proxy. Your 2FA never leaves you. The bigger risk usually sits inside the team, so you can also hide client usernames and block message edits and deletions.

Trust & compliance

What protects a connected account

Encrypted session custody, one dedicated proxy IP per Telegram account, and GDPR-aligned data handling. Everything else on this page builds on these three.

GDPR-aligned data handling

A lawful basis for processing, minimal collection, and your access and erasure rights respected

AES-256-GCM encrypted sessions

Telegram sessions are encrypted at rest with authenticated encryption

Dedicated proxy per account

Every Telegram account reaches Telegram from its own IP, never a shared one

Inside the team

Your biggest data risk is inside your team

Encryption stops an outsider reading a database. It does nothing about a teammate who copies the client list on their last day, or deletes a conversation to cover a mistake. The usual way a Telegram business loses a client is a teammate who leaves with the contact or deletes a conversation. These four controls cover both.

Hide usernames
Teammates work the chat without seeing the client's @username, so the contact stays with the business when they leave.
Hide group member information
Member details in your groups stay hidden from teammates who do not need them.
Block message editing
Nobody can rewrite a message after it was sent. What was said stays on the record.
Block message deletion
Teammates cannot delete messages, so a mistake cannot be quietly removed.

Want a record that lives outside Telegram? The Slack integration relays every chat a seat can access into a Slack channel you pick, as an audit log the employee cannot edit from Telegram.

Data storage

How we protect your Telegram accounts

Two design choices do most of the work: how we hold your session keys, and how every account you connect reaches Telegram.

Two design choices

Learn more

1. Encrypted custody of your Telegram session

To sync chats, send messages and run broadcasts for you, Entergram has to hold a Telegram session. Any tool built on real accounts does. We never hold it in the clear. Every session is encrypted at rest with AES-256-GCM, which protects both confidentiality and integrity, and only the systems that need to use a session can decrypt it.

2. Dedicated proxy per Telegram account

Every Telegram account you connect reaches Telegram through its own dedicated proxy IP. Accounts never share a network fingerprint, with each other or with other Entergram customers, so each one looks like it runs from one consistent location. That lowers the chance of Telegram flagging normal activity: in the last 6 months there were zero bans on Entergram-managed accounts (Entergram's own product data).

Encryption at rest

Sessions are never stored in plaintext. Each one is sealed with AES-256-GCM before it reaches our database, and it is decrypted only inside the systems that use it, only for as long as they need it. The encryption keys are kept apart from the encrypted data, so a database snapshot on its own exposes nothing usable.

If you lose access

Recover your Entergram account through the standard recovery flow. If a Telegram account ever needs re-linking, for example after a change on Telegram's side, disconnect it and connect it again. There is no extra passphrase to remember and nothing to recover from us.

What we hold, and what we don't

We store your Telegram session, because the product cannot act for you without one. We encrypt it, and we keep as little else as possible: your Telegram message history is not stored in our database. Messages are fetched live from Telegram and held only in short-lived caches that expire on their own. What does persist is what you deliberately create: the latest-message preview in your chat list, and the tickets, templates, notes and broadcasts you write. Teammates never see your password or 2FA code. Our Privacy Policy sets all of this out in full, and it governs if the two ever differ.

In practice:

Sessions are encrypted at rest

AES-256-GCM with authenticated integrity checks. A tampered or partly leaked encrypted blob is rejected, not silently accepted.

No message archive

Telegram stays the source of truth for your conversation history, so our database holds no archive of your messages to leak.

Least-privilege access

Only the production systems that genuinely need a session can decrypt one, and every access path is auditable.

Dedicated proxy infrastructure

Learn more

Each Telegram account you connect is bound to its own dedicated proxy IP for as long as it stays connected. Account A and Account B, even in the same workspace, never reach Telegram from the same address, and no IP is shared with another Entergram customer. The result is steadier sessions, fewer false flags and a clean separation between accounts at the network layer.

Additional security measures

Alongside the architecture above, we apply standard hardening across the platform:

HTTPS everywhere, with TLS encryption in transit for every connection
Strict access controls and least-privilege principles
Continuous monitoring for suspicious activity
ISO 27001 in progress and SOC 2 signed with Sprinto, expected during 2027. Neither is certified yet, and we will not imply it is
Secure development practices to prevent common vulnerabilities

Know what moves through each layer

Entergram needs an authorized Telegram session to operate a connected account. The controls below separate that session from the CRM records your team creates and from Telegram-native conversation history.

FAQ

Security questions teams ask before connecting accounts

Does Entergram use Telegram bots?

No. Entergram runs on real personal Telegram accounts, and each connected account is routed through its own unique proxy rather than a shared one.

How do I stop an employee from deleting or leaking chats?

Workspace privacy controls can hide usernames, hide group member information, and prevent users from editing or deleting messages. The Slack integration can also relay every chat a seat can access into one Slack channel as an audit log.

Can a personal account stay private inside a company workspace?

Yes. Sharing is a per-account choice. Each Telegram account is either shared with the workspace or kept private to the person who connected it.

What can an AI app reach through the Entergram MCP?

The AI app signs in with your Entergram account over OAuth and shows the permissions it asks for before you approve. It reaches only chats your connected accounts can already see, and you can revoke its access at any time.

Does Entergram sell contact data or scrape group members?

No. Entergram does not sell contact data and does not harvest members from groups an account has not joined. For outreach, you supply the contact list and Entergram resolves it.

Can we host Entergram on our own infrastructure?

Yes, on the Enterprise plan. You run the deployment on infrastructure you control and choose the data region. CRM records are stored in PostgreSQL inside that deployment, raw Telegram message history stays in Telegram, and single sign-on with Okta is included.
