The most secure messaging app in the world
Only cryptography can guarantee the complete security of your communications
You believe data leaks can’t be avoided?
Don’t give up! Olvid reproduces the confidentiality of a closed-door meeting in the digital world.
You no longer trust the integrity of servers?
For the first time, security does not rely on trusted servers.
You want to protect you personal data?
No identification element is ever transmitted to the servers: the exploitation of personal data is not possible, neither by Olvid, nor by a third party.
Secure your Communications
Right now, easily, at an unprecedented security level
Ease of use
Just install the app on your smartphone and that’s it (quick and easy deployment, completely independent of the solutions already in place in your company).
Enjoy the same ergonomics as consumer applications, plus security.
Exchange texts & attachments and form groups with any Olvid user inside or outside your company.
Security & Privacy by design
Never go wrong, 100% privacy and security systematically guaranteed in a transparent and native way.
Get the best cryptographic security level on the market.
Protect yourself from eavesdropping with end-to-end encryption.
Use Olvid with any smartphone, Android and iOS, regardless of the version.
Scan a QR code
Exchange a PIN code
“94% of data leaks can be traced back to third parties”
Email or instant messaging used to communicate with subcontractors, clients, consultants, lawyers… are quite often at the source of the leak.
“If you build a system where everything comes down to trusting the server, you might as well dispense with all the complexity and forget about end-to-end encryption”
Matthew Green, cryptography professor at Johns-Hopkins University, Wired
Authentication & encryption of data and metadata
No current means of communication can guarantee these 3 components simultaneously.
Encrypted email guarantees user authentication but the security level of exchanges is not satisfactory. Instant messaging
apps offer various encryption qualities but cannot guarantee user authentication. Finally, both email and current instant
messaging leave traces on the servers…
Olvid addresses these three issues in one single app.
Guarantee the use of the right key to ensure that you reach the right person
Use this key properly, with state-of-the-art mechanisms, to ensure that no third party can ever see your exchanges
all the information with this key in order to preserve the anonymity of exchanges
S/MIME and PGP
Focus on authentication
No forward secrecy
Unencrypted metadata in the header
Email can never provide an acceptable security level
Consumer grade messaging
WhatsApp, Signal, Telegram…
Focus on end-to-end encryption
Fallible authentication based on a central server
→ risk of breach
High-security datacenters in Europe
Same security model as WhatsApp
A Major Technological Breakthrough
No longer trust servers to communicate
Our security model is radically innovative. Olvid is the only communication tool that does not rely on servers for
the security of its communications.
Servers get hacked? No problem, it is impossible to access message contents or to reveal user identities. Olvid is
the only messaging app to encrypt all metadata and thus guarantee the anonymity of users. Olvid also guarantees
user authentication, unlike all other messaging systems whose servers act as trusted third parties…
Security is enforced exclusively by cryptographic means (as opposed to access control/passwords)
User identities guaranteed without the need for a trusted third party
No trust in the servers
Security assured even after a server compromise
Ensure the confidentiality of past interactions, even after a key compromise (converstation history remains inaccessible, each message, each file, is encrypted with a single use ephemeral key)
For smartphones in v1, Android and iOS (eventually on desktop, with synchronization and without master device)
Impossible for the operator to know who is talking to whom.
No third party can identify the participants, not even the server. No trace of metadata
What about post-quantum cryptography?
We got you covered!
Resistance of cryptograhic algorithms to quantum computers has been a recurring question for the last few
years. The symmetric cryptography used inside Olvid today is already resistant to this kind of machines, but
this is not the case for the public-key primitives. The reason being that, as of today, no "Post-Quantum"
For this reason, the NIST (National Institute of Standards and Technology) has initiated a worldwide
competition (NIST - Post-Quantum Cryptography)
to select one or more quantum-resistant public-key primitives. The winners should be announced before the end
of 2020. The architecture of the cryptographic engine inside Olvid has been designed from the start to easily
accomodate these new algorithms once they are ready. Thanks to this, we will be among the first to implement
these new post-quantum standards inside a commercial product.

Long lasting collaboration
Cryptography consulting in Paris since 2009, with international reach. Lead by Pascal Paillier, former
director of Gemalto’s “Cryptography and Innovation” unit.
Since Oct. 2019, Olvid has joined the highly prized circle of start-ups selected to integrate platform58, the exclusive incubation program created in 2018 by La Banque Postale offering a tailor-made support to highly competitive and disruptive technological startups.
Wavestone - Shake’Up
Since Sept. 2019, Olvid integrated the Shake’Up acceleration program, created by Wavestone to help their clients successfully carry out transformation and develop promising start-ups. Olvid is hosted in the heart of the firm’s teams and benefits from its consulting expertise and constant flow of contacts.
From 2017 to 2019, Olvid was hosted at Agoranov, an incubator founded by ENS, Paristech, Paris-Dauphine University, Sorbonne University, Inria and sponsored by the Ministry of Higher Education, Research and Innovation, the Île de France region, the Paris City and the European Social Fund of the European Union.
Olvid joined Wilco, the largest start-up accelerator in Paris, in March 2019.
