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configurations (firewall rules, router settings, shared resources, OS hardening) and identify misconfigurations or outdated software.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.

Our ads are being removed. I need someone who can find a solution to this bot attack problem.

My WordPress site has started redirecting visitors to unknown domains. I have a recent, clean backup in place, so your first step will be a thorough malware scan, followed by complete removal of any malicious code or injected files. Once the cleanup is verified, restore the site from my backup, harden its security, and confirm that every page loads safely with no further redirects. Please show examples of past malware-removal work you’ve handled on WordPress so I can see the depth of your experience. I’m particularly interested in the tools or methods you rely on—whether that’s Wordfence, Sucuri, Imunify, SSH-based searches, or custom scripts—so I know exactly how you’ll protect the site going forward.

Cloudflare Zero Trust & Starlink CGNAT Home Network – Project Summary This project involves designing a secure home SASE-style network using Starlink Gen 3 (CGNAT) and Cloudflare Zero Trust to protect internal infrastructure while enabling secure remote access. Because Starlink operates behind CGNAT, traditional port forwarding cannot be used. Instead, Cloudflare Tunnel will create encrypted outbound connections to securely expose internal services without opening inbound ports. The network includes NAS storage, Home Assistant, IoT devices, PTZ/NVR security cameras, UPS monitoring systems, and smart-home integrations (Google Home, Alexa, Apple Home). The architecture must provide secure remote administration while maintaining normal automation functionality. Security will rely...

My website has suddenly started throwing the message, “Error: Server Error – The service you requested is not available yet. Please try again in 30 seconds.” The outage appeared only recently and was not preceded by any obvious code or configuration changes on my side.

Once you locate the issue—whether it points to a misconfigured server, an unhandled 500-level condition, or a resource-limit problem—I expect a clear explanation of what happened and the corrective steps you took. Deliverables: • Diagnosis report outlining the exact failure point • Implementation of the fix and con...

My site is suddenly being flagged with a phishing warning and visitors see a “risky site” message. I haven’t touched the code or added new pages in quite some time, so I need a fresh set of expert eyes to uncover what’s triggering the alert and to get the flag removed. Small task, couple of hours research by someone with the right skills. Current situation • Phishing warning appears on major browsers and link-sharing platforms. • No recent content or code updates on my end. • The site does rely on a few third-party plugins/integrations that could be a vector. What I’m after I want a concise security assessment that pinpoints the root cause—whether it’s injected scripts, compromised plugin files, mixed-content issues, or so...

My site already runs through Cloudflare and basic protection is in place, yet I know the platform can do much more for security. I want a seasoned Cloudflare specialist to go through my current setup, tighten every loose end, and leave me with a hardened configuration I can trust. Scope of work • Firewall rules – Review what I have, remove redundancies, and add precise allow/deny rules and rate limits that match real-world traffic patterns without blocking legitimate users. • SSL/TLS – Move the zone to the most secure Full (Strict) mode, renew or generate any required origin certificates, enforce HSTS and secure ciphers, and confirm end-to-end encryption is flawless. • Bot management – Configure Bot Fight Mode and related features so genuine traffic ...

I need Cloudflare configured so my site automatically blocks malicious or nuisance traffic rather than legitimate visitors. The immediate headache is spam-driven form submissions and crawlers hammering the same pages hundreds of times a minute, so the goal is to stop those two behaviours without slowing genuine users. I already have a Cloudflare account in place; what I’m missing are the right firewall rules, bot management settings, and rate-limiting thresholds. You’ll review my current WAF/Bot Management setup, identify the loopholes that allow automated form posts and excessive page requests, then implement Cloudflare features such as Bot Fight Mode, custom WAF rules, Challenge or Turnstile for forms, and sensible request limits. Deliverables • Documented list of ...
