Our Customer Reviews Speak For Themselves

Our mission is to deliver expert cybersecurity consulting services, implementation, and management in a manner which goes beyond our customers’ security requirements AND industry standards — with the conviction that “CP Cyber is friendly and easy to work with.”

We are more serious about cybersecurity than our clients, which is a testament to our mission and success.

“Bill, Brian, Donnie and the team have been exceptional partners in helping us develop a full cyber security approach for our growing company. Over the last two years, they have provided protection and support with their cybersecurity consulting and MSSP services. Their unique SOC as a Service product (combining two Security Operation Centers) and expertise is well appreciated and hard to find in the Denver market place.”

The team at CP Cyber provided us with a right-sized yet thorough Cyber Security Audit. They were professional, courteous and flexible and took the time to explain issues in layman’s terms. They are delightful and true pros in their field. I would recommend them to everyone. They did a great job for us.


Office Manager

Our organization engaged CP Cyber for a penetration testing and social engineering assessment. I was very impressed by the expertise, thoroughness, and professionalism demonstrated throughout the process. The results and deliverables were far superior in quality and depth than other cybersecurity providers we had worked with in the past. Overall, we were verify satisfied with the experience and will be working with them again in the future.

Eric Peters

Senior Cloud Engineer

“We were in a dire situation when our IT system administrator left with short notice. Thankfully, Cornerstone devoted immediately the resources that we needed to get us through the crisis. Of course, Murphy’s Law struck and we encountered a wide range of additional significant IT issues. We were amazed at the depth and breadth of Cornerstone’s expertise and experience and their ability resolve the issues in an extremely timely basis. All the while they were the epitome of professionalism. I would highly recommend Cornerstone.”

“We’ve been working with CP Cyber for the past year and we’ve been exceptionally impressed with their service and speed. If you’re in the market for network/system security, this is your team.”

Reid Hansen

Business Manager

“I fell victim to a somewhat sophisticated cyberattack and called CP Cyber for help. I’m very glad I did, because within one business day they had made an initial assessment of the situation, picked up my computer for detailed analysis at their office, identified and neutralized the threat, and returned the computer to me, completely cured, for a reasonable price. I was very impressed with the service I received from CP Cyber — these folks are real pros!”

Daniel Kagan


“Fast, responsive, and extremely good quality of work. It was really a pleasure working with Bill and his team.”

Johnathan Maske


“Bill and his team at CP Cyber were prompt, professional, and most of all courteous. Bill’s prior life working in a public accounting firm lent itself well for him to know the demands of our industry. They met with our firm’s leadership team and explained all of the results of their penetration test and vulnerability scan. They explained everything in “non-technical” terms and it really hit home. We are very happy with CP Cyber and would recommend them to any company looking for a great partner in shoring up technical security. We will be working with them again.”

M Pitt

Compliance Officer

“We were so lucky to have found Cornerstone. They were quick to respond and were extremely efficient. They helped us figure out our IT issues that no one else could. Thank you so much Donny and team!”

Keri Farmelo

Office Manager

“Cornerstone to the rescue! They stepped in and really helped us get through a difficult situation. The people we’ve worked with at Cornerstone have been thorough, knowledgeable, resourceful and seem to possess unlimited expertise. They have been beyond professional at all times. tl;dr – They know their stuff—highly recommended!”

Frequently Asked Questions

Is it true you have clients all over the country?

Yes, we are based in Denver, but we have clients all over the country that we protect.

My business has been hacked, can you help?

Yes, we are based in Denver, but we have clients all over the country that we protect.

Is it better for me to hire you once a year to fix stuff, or is it better to hire you on ongoing services?

While we are available to help after a breach or attack, we can also assess the current IT environment and make security recommendations to address critical risks to your business. These recommendations will keep your business from being vulnerable to attacks before they happen.

Based on our experience, the downtime that the business is subjected to after an attack, makes the overall cost of reacting to an attack 10 times more expensive than it would have cost to prevent it.

How do I choose the right cybersecurity company for my business?

We understand that we aren’t the only Cybersecurity company in Denver, but when you are shopping around, please ask the competition what their testing procedures include. They should be a mix of automated scanning of vulnerabilities and manual testing using exploits to confirm the findings. You don’t want someone that will point a scanning at your publicly facing systems and uses the results directly from this tool to give you a report. We can do better than that.

Additionally, after describing your companies systems and IT environment, ask them what what attack vectors they would be using during their fieldwork. These should the applications specific to your company. You do not want a company that performs the same attacks on each of their clients regardless of whether they have Office365 with application development hosted in Azure or large traditional on-site domain-based active directory.

CP Cyber provides all the services, customer care, and attention for protecting our clients and letting them focus on business
