Cheyanne Brown's Review Sourced from Google
Cyber Protect, and its owner Cheyenne Harden, is a wonderful company to work with. Not only is Cheyenne Harden extremely knowledgeable in information, technology, and cybersecurity, but he is also is kind and easy to work with. Him and his company will do everything they can to ensure that your data is secure, protected, and that your technology is running properly. I highly recommend him and his company.
Cindy Luo Review from Google
1.0★
Cindy Luo's Review Sourced from Google
Terrible service. I trusted Cyber Protect LLC to help secure my data, but I still got hacked while under their protection. When I reached out for help, their support was slow, unresponsive, and offered no real solution. They took no accountability and left me to deal with the damage on my own. Completely unreliable and not worth the money. Would never recommend.Edit: Your response is disappointing and frankly evasive. If you have no record of me as a client, maybe that explains why your “protection” failed so miserably. Your slow, unresponsive support and complete lack of accountability left me to deal with the consequences alone. Claiming that neither you nor your clients have ever experienced a breach sounds more like a PR line than reality.If you want to prove otherwise, then start by owning up to your failures instead of brushing off legitimate concerns. Until then, your “enterprise-grade solutions” are nothing but empty words.

Regression testing: Analyzes the stability and functionality of the app after a bug has been fixed
