End-to-end encryption
Some things should stay
between you.
Private messages. Protected conversations. Keys under your control.
Encryption engineered into the products your people depend on.

Recipient-controlled key
Ready to encrypt the example.
Illustrative only. No messages are sent and no encryption runs in this demo.
Your architecture. Your deployment. NDA by default.
01 / Trust, by design
The right people can read it.
The infrastructure doesn’t need to.
Privacy is an architectural decision. We define who can decrypt, where keys live, and how trust moves through your system.
Private at the endpoints
Messages are encrypted before they leave the sender and opened by authorized recipients. The relay handles ciphertext.
Deliberate key ownership
Decide where keys live, who can use them, and what happens when a device is replaced or lost.
Identity you can verify
Device enrollment, recipient verification, and group membership are part of the security design.
A design you can review
Document the protocol choices, trust boundaries, and operational assumptions so the system can be assessed.
Security beyond the message
Strong encryption.
A complete plan.
The protocol is one part of the system. Devices, people, and operations need the same care.
Endpoint security
A compromised device can expose messages after decryption. Device policy, updates, and revocation belong in the plan.
Metadata & retention
Encryption of content does not automatically hide who communicates or when. Scope metadata collection and retention separately.
Recovery & access
Define recovery before deployment. Restoring access, adding devices, and changing membership must preserve the intended trust boundaries.
Hosting & operations
Align deployment location, administrative access, and operational responsibilities with your organization’s requirements.
02 / Where we can help
Privacy for your product.
A clear place to start.
Build a new capability or strengthen an existing system. We scope the work around your application and operational needs.
01 / MessagingE2E messenger
Private one-to-one and group messaging for your application, with endpoint encryption, device identity, and session management scoped together.
Starting at$10,000 CAD

02 / CommunicationsE2E voice & radio
Protect voice calls and push-to-talk content between authorized devices, with dispatch permissions and group membership designed around your operation.
Starting at$15,000 CAD

04 / ArchitectureCustom session protocol
For specialized deployment requirements: a documented session layer built on established cryptographic primitives, with a defined independent review path.
Starting at$25,000 CAD

03 / From requirements to reality
Start with the threat model.
Build with intention.
A structured engagement, with the assumptions, responsibilities, and review requirements made explicit.
- 01
Define the threat model
Identify the information to protect, the authorized readers, and the systems or actors that must not have access.
- 02
Design the architecture
Select the protocol, device identity model, storage approach, and integration points for your application.
- 03
Build & validate
Implement the agreed scope, test session and device lifecycle behavior, and establish the security review plan.
- 04
Deploy with ownership
Document key management, revocation, updates, and operational handover so your team can run the system.
04 / A little more clarity
Privacy is complex.
The conversation shouldn’t be.
Let’s work through what matters to your product, your people, and your deployment.
Talk with our engineersTLS protects a connection between a client and a server. The server may still read the content. End-to-end encryption protects content between authorized endpoints, so a relay server does not need the keys that decrypt it. The two can be used together.
Key ownership is defined during architecture and scoping. For end-to-end content, decryption keys belong within the authorized endpoint trust boundary. Device storage, hardware-backed protection, and administrative responsibilities are selected for your deployment.
We assess your application, devices, communication stack, and deployment constraints during discovery. Messaging, files, voice, and push-to-talk can require different integrations. The proposal specifies what can be supported and what needs to change.
We start by evaluating established protocols and maintained implementations against the requirements. A custom session layer is an option for specialized needs, with a written specification and review plan. Customization does not automatically make a system more secure.
End-to-end encryption protects the communication path, but an authorized endpoint can read messages. Device compromise, backups, local storage, and recovery need their own controls. Enrollment, revocation, and device hardening are scoped as part of the wider system.
Prices are in CAD for a scoped engagement: key custody from $8,000, an E2E messenger from $10,000, voice and radio from $15,000, and a custom session protocol from $25,000. Final deliverables, review requirements, and pricing are defined in the written proposal. Applicable taxes are additional.
