My company-owned laptop is still physically with me, but a former employee encrypted its primary SSD with BitLocker and tied the keys to his personal Microsoft account. The machine runs Windows 11 and will boot all the way into Windows; the problem is that every business-critical volume remains locked, leaving me without access to files that are now central to an internal theft investigation. I need an experienced security professional who can: • Bypass or otherwise unlock the existing BitLocker protection without that user’s Microsoft credentials • Extract a full, verified copy of all user data (including deleted items) • Preserve evidence integrity and provide a concise forensic report that could hold up in potential legal proceedings You may guide me through ...

I have an STC 5G connection running on a TP-Link Archer NX200 router. The connection is behind CGNAT, meaning I do not have a real public IP. I am looking for an expert to provide a solution to get a Dedicated Static Public IP so I can remotely access my internal network (Router management, SIP devices, etc.) using my noip DDNS Conditions: I cannot upgrade to a Business SIM card. I do not want to run a local PC 24/7 as a bridge. I just need a working Static IP solution that routes traffic from the outside directly into my local network. Please propose your method and how we can implement i

I’m looking for an experienced ethical hacker to probe my hybrid network—both wired and wireless—with the sole aim of uncovering security vulnerabilities. Scope and focus • Map the entire network topology, including any VPN entry points, routers, access points, and key servers. • Perform vulnerability scanning and targeted penetration testing against internal and external segments. • Validate findings through exploit proof-of-concepts where safe and appropriate, ensuring no disruption to production traffic. Deliverables 1. A clear, prioritized vulnerability report that explains each issue, its risk rating, and the affected assets. 2. Screenshots or logs that support every critical or high-risk finding. 3. Action-oriented remediation recommenda...

I’m looking for a fresh, expert set of eyes on my already-launched SaaS. The priority is a thorough check of both Security and Performance. I’ll share the exact tooling, checklists, and testing methodologies I currently use so you can step straight into the review process without guessing which scanners, profilers, or penetration-testing suites to run. Here’s how I see the engagement unfolding: you explore every security layer—from authentication flow to data storage—and benchmark performance under realistic load. When you’re done, I’d like a concise report that highlights the key findings, high-impact risks, and the quick wins that will give me the most immediate improvement. No need for a long-form narrative or slide deck; a sharply written summ...

I run a small but growing company whose staff is scattered across several time zones. Because we have no physical headquarters, every employee depends on a reliable, secure technology stack to stay productive. I need an experienced IT systems manager who can step in and own that environment from end to end. Day-to-day you will: • Monitor and maintain all user workstations, keeping operating systems, apps and security patches current. • Administer accounts, permissions and backups in our cloud services (you’ll help me choose or streamline them where necessary). • Act as first-line support for the team: diagnose connection issues, resolve software conflicts and keep Zoom—our primary meeting platform—running smoothly. • Document processes so onboar...

I need hands-on hardware support for a group of office desktops and laptops. The priority is hardware support, and the machines are showing a mix of performance slow-downs, intermittent hardware failures, stubborn software-installation problems, and the occasional network conflict that boots them off our LAN. You’ll be expected to run full diagnostics, identify failing components, repair or replace them, install the required software, and confirm that each computer rejoins the network cleanly. Experience with Windows 10/11, BIOS utilities, imaging tools such as Clonezilla or MDT, and basic networking commands will make the work go faster. Deliverables • A brief troubleshooting report for every affected machine • Completed repairs or documented recommendations when repla...

I’m ready to invest time in practical, one-on-one guidance that demystifies how attacks really unfold and, more importantly, how to spot and stop them. My background is purely beginner, yet my responsibilities will soon include supervising an IT/security team, so I need a clear, experience-based understanding of the attacker’s mindset. Focus areas • Network security: packet sniffing, basic exploitation, lateral movement, and network-level hardening. • Social engineering: phishing set-ups, pretexting scenarios, and the defense playbook that counters them. Learning format We will work inside pre-configured virtual machines you supply, where you walk me through the build-break-fix cycle: launching a representative attack, detecting it with common tools (Wireshark...

I’d like my Windows laptop configured so my children (aged 10-15) can use it safely without constant supervision. The setup must: • Enforce daily and weekly time limits that automatically log them out when the allowance is reached. • Block a list of questionable or distracting websites I will provide, and make it easy for me to add or remove sites later. • Prevent access to specific applications and system areas I choose, while leaving school-related programs untouched. • Let me trigger a remote log-off or shutdown from my own account or phone whenever homework needs attention. I don’t have a preferred tool yet and would appreciate your guidance on whether the built-in Windows family settings are enough or if a third-party suite (e.g. Qustodio, Norto...
