I run an e-commerce site and need a specialist to connect the domain to Cloudflare, tune it for best practice security, and make sure the key response headers are in place. Here is what I’m after: • End-to-end Cloudflare configuration on my primary domain, including DNS records moved or verified inside the Cloudflare dashboard and the site fully proxied behind their network. • An active, valid SSL/TLS chain so every page loads via HTTPS without mixed-content warnings. • Implementation of modern security headers—at minimum Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options—plus any others you recommend for an online store. • A quick performance sanity check (caching rules, Brotli, image optimization, etc.) so I’m ge...

I’m dealing with an unwanted, fake browser that has embedded itself in my Windows machine and keeps hijacking my default settings. There is no antivirus installed at the moment, so I need a clean-up plan that relies on portable or web-downloadable tools (for example, Malwarebytes, Windows Defender Offline, AdwCleaner, or any reputable removal utility you recommend). The job is urgent—I’d like the system back to normal as soon as possible. Once the rogue software is gone, please restore my default browser settings and confirm that no residual processes, registry entries, or scheduled tasks remain. Deliverables • Complete removal of the fake browser and any associated malware • Verification that all browser and system settings are back to their legitimate st...

Our BGMI (Battlegrounds Mobile India) infrastructure occasionally freezes when traffic surges. I want to put a permanent stop to that by building a preventive DDOS shield that covers every critical touch-point—login, in-game communication, and matchmaking. You will begin with a quick audit of the existing network layout and traffic patterns, then design and deploy a solution that blocks volumetric and application-layer attacks before they can overwhelm the servers. I expect minimal additional latency for legitimate players, clean documentation of every rule or service introduced, and a repeatable playbook I can apply to new nodes as we scale. Deliverables • Security architecture diagram and written rollout plan • Hardened configurations applied to the login, game, a...

I need a seasoned ethical hacker to carry out a full-scope security assessment of my environment. The end goal is simple: uncover any vulnerabilities before malicious actors can exploit them, then give me clear, actionable steps to fix them. Please outline your relevant experience when you reply—real-world projects, certifications (e.g., OSCP, CEH), and any notable results will help me understand how you approach engagements like this. Scope • Reconnaissance and vulnerability discovery • Exploitation and privilege escalation (within agreed boundaries) • Post-exploitation risk analysis • Clean, well-structured reporting that ranks issues by severity and urgency Deliverables 1. Executive-level summary (non-technical) 2. Detailed technical report...

I am seeking a cybersecurity specialist to support my company’s security efforts by performing the following tasks: Analyze Splunk vulnerabilities that I will provide; Document these vulnerabilities thoroughly, including identifying any related case studies, previously documented examples (e.g., academic articles or CVEs), and all possible remediation strategies;

I manage and have noticed drops in impressions and a few stubborn pages that refuse to appear in Google. My immediate goal is to uncover and correct every crawl-related or indexing problem that might be holding the site back. Technical focus • Your first task is to diagnose crawl errors, sitemap irregularities, conflicts, duplicate canonicals, or anything else that could be blocking or confusing search engines. • Along the way, please carry out a full-scale technical audit so we can catch secondary issues early instead of repeating this exercise later. Deliverables 1. A clear audit report (PDF or Google Doc) summarising each issue you uncover, the root cause, and the impact on indexing. 2. A prioritised action plan with step-by-step fixes. 3. Implementation of t...

I run five Magento 2.4.7-p1 ecommerce stores on a single dedicated server and have discovered a redirect to the malicious domain lanhd6549tdhse.top. I need someone to trace every trace of this malware, remove it cleanly, and harden the server so the infection does not return. A fresh, full backup from last night is ready, and an antivirus already runs on the machine, but the infection slipped through. What I expect from you: • Thorough file-system and database scan to locate the malicious code, scripts, or cron jobs referencing • Clean removal without disrupting live sales or order data • Security patching of Magento 2.4.7-p1 core and extensions where relevant • Server hardening suggestions and implementation (firewall rules, permission tightening, malware signa...

I need an experienced cybersecurity engineer who knows how to secure manufacturing OT environments from the ground up. Our plant floor runs a mix of SCADA, PLC and DCS systems on VMware / ESXi virtual infrastructure, and I’m kicking off a project that tightens every layer—from the hypervisor to the operator workstation—while staying fully aligned with ISA/IEC 62443 and NIST guidelines. Scope of work • Assess the present security posture, map risks to ISA/IEC 62443 zones & conduits, and deliver a concise risk report. • Recommend and implement security improvements that will not disrupt production or existing integrations. • Verify every change through functional testing and validation before sign-off. Core technical tasks • Deploy and tune...

I need a certified ethical hacker to put my production web application through a thorough vulnerability assessment. The assignment is strictly white-hat: you will have full, written authorization to probe the app so long as no customer data is altered or deleted. My sole objective is to identify every exploitable weakness you can find—misconfigurations, logic flaws, injection points, broken authentication, anything that could be abused in the real world. Tools such as Burp Suite, OWASP ZAP, Nikto, or custom scripts are welcome as long as the methodology is reproducible and aligns with current OWASP Top 10 practices. Deliverables • A clear, well-structured report that lists each vulnerability, proof-of-concept evidence, severity ranking, and recommended remediation steps....

I need an experienced network engineer to keep an existing Wide Area Network running smoothly through regular maintenance and timely updates. The environment already functions well; my priority is to prevent surprises, apply security patches, review configurations, and quickly resolve any performance drift before end-users notice. Here’s what I will expect from you: • A clear maintenance schedule that covers firmware/software updates for routers, firewalls, and edge switches. • Proactive monitoring suggestions and the tools you prefer for alerts and reporting. • Thorough change-control notes each time you touch the network so I can track what was updated, why, and how to roll back if needed. • A short weekly health summary highlighting bandwidth trends, l...

I need my new FortiGate 80F installed and fully integrated into the existing LAN so that the whole environment benefits from stronger security without sacrificing speed. The key outcome is a balance of protection and performance: traffic must be scanned, filtered, and shaped while keeping latency low for everyday business applications. Configuration requirements • Security posture – enable intrusion-prevention, anti-virus, and web filtering profiles that block known threats and unwanted content. • Internet use control – create policies that (a) block or allow specific websites, (b) throttle bandwidth for heavy-use categories like streaming, and (c) log user activity for later review. • Performance tuning – apply best-practice SD-WAN and bandwidth all...
