Mordy Fried
Hi, I'm Mordy. I spent several years of my career building out a robust security program for one of the nations largest e-commerce platforms.
I had a sizable budget and a dedicated team at my disposal.

And that left me with a troubling question:
Question icon

How can the average mid-size Enterprise stay secure and avoid a cyber attack without breaking the bank?

Attention icon

The process is overwhelming.
Security measures are ambiguous, cumbersome and not to mention costly.

But worst of all?
Often times, the holy-grail, time-vaunted cyber security methods don’t actually do anything to lower the risk.

They’re expensive tools that people chase after, while forgetting about security essentials.

Low price icon

That means burning through tens of thousands of dollars–while the doors stay wide open for cyberattackers.

Idea icon

The answer?
It’s not glamorous. It’s not romantic.
It’s simple. And it works.

It starts with three fundamentals:

EMPLOYEE
AWARENESS
ANALYZE YOUR
RISKS
FORTIFY YOUR
ENVIRONMENT
01

EMPLOYEE AWARERNESS

Your employees are the gatekeepers to your security. Do they know how to differentiate between fraud and genuine to keep your business safe?

02

ANALYZE YOUR RISKS

If you are running Server 2003 on your domain controller, I don’t need to run a 30k test to tell you you're vulnerable. I can tell you that – and where else you’re at risk – by inspecting and assessing your setup.

03

FORTIFY YOUR ENVIRONMENT

Seal the entry points before hackers find them. We’ll tell you what the best solution is to alleviate your risk, plus guide the implementation.

And that’s the Keystone way:

Giving businesses a pain-free, overwhelm-free way to keep their businesses secure without breaking the bank.

Meet Keystone’s chief. Mordy’s extensive background in cyber security began with him as a simple IT technician, removing viruses and setting up firewalls. Seeing a need in the industry, he eventually designed and taught a course to others looking to become technicians. He then led the cybersecurity team at B&H Photo, NYC. He’s a genuine, get-your-hands-dirty doer who moonlights as a frozen pizza connoisseur. He understands the complexities of cyber threats, and the limitations of standard solutions.
