A single app to securely manage all your
enterprise communications for free, for life.
Combine with Ceerus Connectors and
Ceerus Enterprise to take control of your
communications and choose where it is
stored and who can access it.

Built for enterprise

Ceerus App was built from the ground up for the
enterprise environment. With the increase in remote
working, staff and customers are exposed to a wide
range of cyber risks.

Phishing attacks

Ceerus App authenticates every user to
ensure that the person on both sides of the
call are who they say they are. This starts
from the second the user is onboarded to
every single call that takes place, which is
encrypted using ID-based encryption to
ensure every conversation is authenticated
on both sides.

Eavesdropping

Ceerus App encrypts all data - whether it’s
voice, video or chat – using the same
end-to-end encryption to prevent
eavesdropping.

SS7 attacks

Weaknesses in the telecoms network can
be exploited by hackers to expose your
communications. Ceerus encrypts all data
“Over The Top (OTT)” to provide an
additional level of security on top of your
telecoms networks to prevent these types
of attacks.

Third party Protection

We will never share your data with
advertisers or monetise your data in any way
so you can be sure that your data always
stays private.

Hosting and access control

With Ceerus Enterprise, you control
exactly where the data from the Ceerus
App is stored, who hosts the servers and
who has access to it. We provide
complete control of the entire
infrastructure to our customers.

Secure from the
ground up

Ceerus App was built with security at
the core of every design decision.
