I am ready to move our organisation to CMMC Level 1 and need a specialist who can guide the entire process from assessment through remediation and documentation. The scope spans three core areas—network security, data protection, and user access control—across all production servers, employee workstations, and our small fleet of mobile devices. Our environment is a typical Microsoft-centric stack with a mix of on-prem VMware hosts, Office 365, and a few SaaS applications that handle Federal Contract Information. What I need first is a concise gap analysis mapped to CMMC Level 1 requirements (aligned with NIST 800-171 Rev 2). From there, we will prioritise fixes, implement the missing safeguards, and collect artefacts that demonstrate ongoing compliance. I expect clear document...

I need a reliable partner who can jump in as first-line support for my staff and keep everyone productive. The focus is on everyday desktop and laptop issues—anything from random hardware glitches to blue screens or slow performance. On the software side you’ll be handling operating system troubleshooting, rolling out application installs and updates, and resolving antivirus or other security alerts before they spread. Network hiccups are another pain point. Expect tickets about dropped internet connections and Wi-Fi dead zones; you’ll diagnose, reconfigure, or escalate as needed so users aren’t offline for long. Although servers and other infrastructure sit in the background, smooth collaboration with my existing IT team is essential when a problem touches their...

I’m ready to have my website professionally stress-tested so I can patch every weak spot before it becomes a problem. The engagement centres on two critical areas that hold our most sensitive logic and data—the Login System and the User Data Storage modules. Within those components I want you to probe specifically for SQL Injection, Cross-Site Scripting (XSS) and Broken Authentication issues, emulating real-world attack scenarios while staying fully within ethical boundaries. Industry-standard tooling such as Burp Suite, OWASP ZAP, sqlmap, or their equivalents is expected so results are reproducible and mapped against OWASP Top 10. All findings must be compiled in a comprehensive, developer-friendly document that not only confirms each vulnerability but explains impact, suppli...

I’m a complete beginner in wireless security and want to build solid, practical skills in penetration testing for Wi-Fi networks. Over a series of one-on-one sessions, I’d like you to walk me through fundamentals, tools (Kali Linux, Aircrack-ng, Wireshark, etc.), attack simulations, and safe lab setup so I can eventually plan and execute my own wireless assessments responsibly. Please share examples of past work that prove you’ve carried out real-world wireless engagements or successfully mentored others in this niche. Concrete demonstrations—screenshots, anonymised reports, short video clips—help me judge fit quickly. We’ll meet online, screen-share, and practice live. Each session should end with actionable homework and clear checkpoints so I can tra...

The latest patch wiped out every pointer offset my companion app relies on, so most of its memory reads now return garbage and several packet handlers no longer align with the game’s updated structures. I need an expert who can jump straight into the new build, reverse the changed layouts, and hand back corrected offsets (and any packet-structure tweaks you discover) so the tool is fully functional again. Here’s what success looks like for me: • A clean list of updated base addresses, dynamic offsets, and any changed pointer chains tested on the current live client. • Confirmation that each fix restores the original in-game features of my app without crashes or desync. • A brief summary of any packet format adjustments you uncover while tracing traffic so I ...

My wired Ethernet network has stopped working, and I need a skilled technician to get it back online quickly. I’ve already ruled out basic cable swaps, so I’m looking for someone who can: • Diagnose the root cause of the outage (switch, patch panel, NIC, or configuration). • Walk me through any testing steps I should perform on-site (ping, traceroute, link-light checks). • Provide clear, step-by-step instructions or remote-session support to restore connectivity. • Verify that all connected devices regain stable internet and LAN access once the fix is applied. • Offer a brief preventive checklist so I can avoid the same issue in the future. I can share photos of the rack layout, current IP scheme, and error messages from the router and switch interfac...

I have a small office network—fewer than twenty endpoints—that I want thoroughly examined for weaknesses. The immediate focus is a vulnerability assessment combined with a full network-security audit. Pen-testing isn’t required right now, but I would like the audit to be detailed enough that we could progress smoothly to active exploitation tests later if needed. Scope – Map every device and service, then scan using industry-standard tools such as Nmap, Nessus or OpenVAS. – Analyse configurations (firewall rules, router settings, shared resources, OS hardening) and identify misconfigurations or outdated software. – Provide a clear, prioritized remediation plan. Critical issues first, followed by medium and low-risk findings. – Conclude wit...

Yesterday I noticed that every message and folder in my Hotmail account had vanished after an unauthorized login. I have since taken back control of the mailbox and switched on two-factor authentication, but Microsoft support told me they are unable to restore the data. I still need those emails. I’m after someone who knows the ins and outs of / Microsoft 365 back-end recovery, server-side retention, and forensic mail restoration. If you can locate and reinstate the deleted items—whether through the Recoverable Items folder, legacy PST pulls, or other Microsoft recovery channels—and then harden the account so this can’t happen again, please let me know your approach and an estimated timeline. Acceptance criteria • All recoverable emails and folders resto...

I need a reliable person located in the United States who can keep my personal laptop safely at their place, plug it in to power, and turn it on once every day. There are no special tasks to run—simply boot it up, confirm it’s online through your regular, stable internet connection, and let it sit for a moment so remote services can sync. After that, you can shut it down again. What matters most is trustworthy, secure storage in a clean, smoke-free environment, and the discipline to power it on daily at roughly the same time. No dedicated network, VPN, or extra equipment is required on your side; a standard home broadband line is sufficient. If you can provide a safe spot, dependable internet, and consistent daily availability, let’s talk about the hand-off logistics an...
