Enterprise-grade secure communication
Reimagined for how your teams actually work. CIRRUS brings encrypted communication into one sovereign platform. Complete security, without compromising productivity.
Today’s communication is a liability
From data leaks and corporate espionage to guest access sprawl and consumer apps leaving files on personal phones, enterprises pay a rising price for using tools that were never built for them. CIRRUS closes every one of those gaps.
Secure collaboration inside and outside your organization
Create isolated units for departments, joint ventures, and external partners. Everyone works inside the same app; nobody sees anything they shouldn't.
Departmental separation
Spin up sub-departments with their own membership, permissions, and channels. Cross-team leakage becomes impossible by design.
External Partner Rooms
Invite vendors, counsel, auditors, or bankers into a walled unit. They collaborate inside CIRRUS without ever seeing your wider directory.
Directory isolation for guests
Invited guests see only the members they're meant to see. No org-chart discovery, no lateral movement, no cold outreach.
Central governance
Admins provision, revoke, and audit every business unit from one dashboard. Stand one up in minutes; retire it in seconds.
Controlled Corporate Communications
Hardened server setup with advanced protections to prevent unauthorized access, breaches, or tampering.
End-to-end encryption
Messages, media, voice, and video calls are secured with 256-bit AES E2EE. Keys rotate frequently for forward secrecy.
Device binding
Each user is bound to a device-specific code issued from the admin panel. The app opens on that device and only that device.
IP whitelisting
Users connect only to the CIRRUS application server. No third-party route, no external gateway, no exceptions.
Fail-safe login system
Under duress, a secondary passcode triggers a clean wipe of chats and data behind what looks like a routine software update.
Anti-penetration security
Zero unauthorized access, zero data leaks. Every entry point audited, every action logged.
Private server architecture
Deployed on your infrastructure or a dedicated cloud tenant. No third-party data access, complete autonomy.
A private workspace inside your secure app
CIRRUS gives every user a drive-like space for notes, documents, and live spreadsheets with the same encryption, server isolation, and admin controls as your chats. Work sensitive numbers and confidential documents without ever leaving the platform.

Organize notes, files, and attachments into colour-coded folders. Rich formatted text, checklists, tables, images, and file attachments in a full-screen editor. Nothing ever touches the device.
Build Excel-style sheets with formulas and calculations inside the app. No exporting to third-party tools, no shadow copies on personal drives.
Draw freehand sketches or record voice memos directly inside any note, useful for meetings, site visits, and quick captures.
Tag notes for retrieval, search inside any note, and forward an entire note (with all its content) into a chat.

Every note, every sheet, every attachment is encrypted on the server. Admin remote-wipe applies to all of it.
Enterprise-ready, right down to the details
Beyond secure chat, CIRRUS ships with the personalization and polish that make it usable across every corner of your organization.
No data on device
Chats and files are stored on private servers and loaded only when the app opens. Nothing lingers on the device.
Rooted device blocking
The app refuses to open on rooted or jailbroken devices, cutting off a major class of attack.
SIM-to-mobile-number binding
The app works only with the SIM and number registered by the admin. Swap the SIM, lose access.
Media export block
Photos, videos, and files stay inside CIRRUS. Nothing can be forwarded, saved, or exported outside the app.
Screenshot & screen-record prevention
Users cannot capture the screen while inside CIRRUS on any supported OS.
Custom branding
White-label the app with your identity: logo, colors, splash screen, and login.
Themes & personalisation
Users choose between light and dark modes, five curated accent colours, and five typefaces, with notification preferences configurable per feature.
Indian numbering system
Toggle numeric display between international format (millions, billions) and the Indian system (lakhs, crores). Financial data, in the format your team actually reads.
