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.”

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!”

Our Penetration Testing Services

Our internal and external penetration testing services involves our security engineers testing your network while acting as ‘ethical hackers’ to determine any weaknesses

Our penetration testing company performs security testing on your applications to see if unauthorized users are able to modify data, disclose information or steal logged-in user sessions.

Our security engineers perform penetration testing against all of your physical security controls. We attempt to bypass locks, keycard readers, and cameras to simulate a physical breach of offices or data centers.

WiFi networks are often a huge gap in your security posture that hackers can exploit. We test your wireless security to identify weak passwords and unsecured access points.

The human element is always a big risk factor in network and web application security. We see how easy it is to fool employees into giving away passwords or network access.

Frequently Asked Questions

What is a penetration test?
A penetration test is performed by cybersecurity experts that are hired to find areas of weakness in the cybersecurity of a company’s IT environment. A report is provided to the company so that they can focus their money and time on addressing the most critical findings to reduce the overall risk of their company. A penetration tester is trained to emulate a real attacker that will use the latest exploits to gain unauthorized access and escalate privileges.
Why should we have a penetration test performed?
When it comes to cybersecurity the cost of reacting to an attack is much greater than being prepared and avoiding an attack in the first place. In 2019 the average cost of a cyber attack was $4.6 million. Penetration tests help avoid this by showing your IT team where the security holes are so that they can fix them before an attack happens. Without a thorough penetration test your environment may have some vulnerabilities your IT team is unaware of.   Also, certain industries that deal with sensitive data such as financial data are required by law to have an annual penetration test.
How does a penetration test differ from an automated vulnerability scan?
The first step in performing a penetration test is “information collection”. We gather information in a variety of ways including automated vulnerability scanning. After scanning, we review the results and adjust our strategy for manual testing. We may change the exploit we use on publicly facing systems, or attempt a different attack vector all together based on the results. We find that our competitors use the results of the vulnerability scan to provide their clients with reports and call it a penetration test. Naturally, these competitors can charge less for their “penetration test” so be careful when shopping for cybersecurity companies.
What penetration test documentation should I expect to receive when the test is complete? How are the findings documented?
Please contact us for a redacted sample of a penetration test report we have given to a client. Our reports are written based on findings from the manual testing performed by our penetration testers. The penetration tester that performed the work will include a description of the attacks performed, the vulnerability related to these attacks, the risk, and the impact to your business. In addition, the report will include vulnerability scan results. Our team will be available to present the findings to the client’s IT team as well a presentation to upper management.
