Software Development Review from Lori Feld Oakley
Our Services organization is scaling quickly and we urgently needed a custom software application to automate our workflows, without breaking our annual budget. CodeStringers was the perfect fit, supporting us from ideation through go-live and everything in between. They innovated, hit their deadlines and released an amazingly high quality application that decreases our internal costs and improves our reputation with our customers. It would not have happened without CodeStringers.

So they can not only build a product for you but they can make sure that the product you want to build is likely to succeed in the marketplace.

The dashboard Perimattic delivered is minimal, well-structured, and very user-friendly. Small touches like the layout, flow, and clarity of controls make a big difference. Great work by Gaurav and his team.

Great Customer Service - just had a great one on one with Mr. J. Hobson of E-Platform Marketing. Website needed much attention and updates and he has been most helpful and patient. Product knowledge made it so doable and very easy to work with in getting things up to par. Very willing to get real results to keep things running smoothly. Patience is key in this industry and thank you for it! I highly recommend.

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 L'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.
