Stop the bots

The scale of malicious online activity is enough to give anyone pause for thought. Bots alone account for a sizeable percentage of all web traffic, and they’re getting better at mimicking human beings. And on a parallel course, malware is rapidly evolving both in terms of efficacy and stealth.

And with social engineering an ever-present and ever-escalating problem, the challenges that organizations face in defeating these threats is sizeable. Sizeable, but not insurmountable; Callsign’s technology is there to give businesses a winning edge in the fight for a more secure future for everyone.

VPN & spoofing detection

For years VPNs have been seen as a way to protect networks. The trouble is as they’ve become more accessible to consumers, they’re also letting them access content in restricted locations.

Whether it's content licensing to security access or privacy laws, location restrictions are in place for a reason.

We’ll detect whether a user is masking their location and provide you with the tools to orchestrate what action you want to take.

And there's more...

Assurance that your users really are who they claim to be is incredibly important. It’s also important to have the assurance that your ecosystem can adapt to new and evolving technologies, changes in regulations, and your own ambitions.
