Hi there, As an experienced professional with an unwavering commitment to delivering quality results, I firmly believe that I am your best fit for this project. I've successfully carried out numerous assignments that involve technical writing, proofreading, SEO, Content Writing, and Web Designing. Many of these tasks required a thorough understanding of intricate system designs, and I have not only met but exceeded expectations in each instance. While my background may differ slightly from the nature of your project, my solid proficiency in technical areas and web development puts me at a unique advantage. For instance, my experience utilizing technological platforms such as: PHP, Codeigniter, Laravel, Wordpress, Jquery, Ajax, HTML5, CSS3, Bootstrap and Backend SQL Databases will be particularly valuable in building a secure PC Control Service for Windows. Best regards Bharti

Your project deserves top-tier execution. My team delivers every time. I understand the need for a Windows service that blocks unauthorized URLs, restricts USB access, and enforces pre-approved applications by digital signature. Our expertise lies in developing secure, seamless, and integrated solutions. While I am new to freelancer, I have tons of experience and have done other projects off site. Ready to discuss achieving your project goals. Let's connect. Regards, PD Theron

Hi, I've reviewed your requirements in the attached document and am confident in delivering Phase 1. I’ve previously built tamper-resistant Windows services using C# and .NET that interact with system-level APIs for USB control, URL filtering, and application validation via digital signatures. The key parts of your spec — blocking unauthorized access, reading local configs, and logging enforcement actions — are all familiar territory. My estimate for Phase 1 delivery is 10 working days, and my budget for this scope is $100. This includes full source code, documentation, and a tested installer that runs in your environment. A couple of clarifications before I proceed: Do you expect real-time URL blocking via network hooks, or should it rely on browser-level or DNS-layer blocking? Also, is there a preference for how USB devices are whitelisted — by class or hardware ID? Looking forward to your feedback and environment requirements.

I am a perfect fit for your project as I specialize in developing seamless and integrated systems. While I am new to freelancer, I have tons of experience and have done other projects off-site. Specifically addressing your requirements, I will build a Windows service that blocks unauthorized URLs, restricts USB access, and enforces pre-approved applications by digital signature. Configuration and logging will be managed through a local config file. I confidently commit to delivering a fully operational Phase 1 within your specified timeline and budget, with all requested documentation and setup. I would love to chat more about your project! Regards, Brandon Mitchell

Hello, I’ve reviewed your project requirements. Technically, everything is possible, but some features require deeper system access due to Windows security limitations. ✅ Easy to Implement: URL whitelisting (hosts + firewall + browser config) USB storage blocking (WMI + registry) App control using digital signatures Client as a Windows Service HTTPS communication with API Web admin (Laravel/Node.js/Django) with RBAC Policy sync, heartbeat, logging ⚠️ Moderate Difficulty: Making the service non-stoppable: needs GPO, recovery settings, or WDAC Blocking all browsers reliably: requires proxy or system-wide filtering ? Advanced (Low-Level Access): Allowing only specific USB device types (e.g. keyboard, mouse): requires hardware ID filtering Full termination protection: needs kernel-mode development Remote shutdown: possible but antivirus may block it without elevated rights All features are doable with proper planning and secure implementation. Note: I previously built a smaller version of this on Windows XP. I may not find that old code, but I can develop a new, modern version from scratch.

As a seasoned Web Developer with a strong focus on Software Development, I believe I am the perfect fit for your R&D project. My extensive experience in both front-end and back-end development allows me to bring a comprehensive approach to tackling your specific requirements in creating a secure PC control service for Windows. Having developed numerous complex applications, such as creating access restrictions and applying digital signatures, your project aligns perfectly with my skill set. Additionally, I have worked on projects requiring heavy database management and integration, which would be vital in implementing the background service aspect of your service; ensuring it is not stoppable by normal users. With me, you can expect more than just code – I'm diligent about providing clear documentation and regular communication throughout the process. If awarded this phase 1 of your project, you will receive an optimized tested application that works seamlessly in your environment along with comprehensive source code, installation/configuration document and consistent post-delivery support. Furthermore, as per your requirements
