My network edge relies on a Sophos XG appliance and a Fortinet FortiGate unit. Both devices are in production, but their current configuration is a mix of legacy rules and quick fixes that now interfere with performance and security. I want a seasoned firewall engineer to step in, examine every setting, correct what is wrong, and design a clean, least-privilege rule base. Scope of work • Configuration – back up the existing setups, remove or refine redundant rules, and align all interfaces, NAT, VPN, IPS and logging options with best-practice guidelines for Sophos SFOS and FortiOS. • Troubleshooting – identify and eliminate the intermittent drops we see on site-to-site VPN and outbound web traffic. Validation must include live traffic tests and log review. &bul...

I operate a cluster of Windows Server 2019 machines and need an experienced set of hands to keep everything running smoothly. Your focus will be three-fold: maintaining the servers themselves, getting our Veeam Backup & Replication environment dialled-in, and stepping in whenever a network hiccup or whitelist request appears. On the Veeam side I already have repositories in place; what’s missing is a clean, reliable backup configuration and the regular monitoring that guarantees every job finishes without warning bells. Restoration testing and documented recovery steps will be part of the routine so we can prove our RPO/RTO targets at any moment. Networking support centres on troubleshooting issues as they arise and processing whitelist updates for partners and applications tha...

I’m in the middle of an ongoing project and have run into a few stubborn issues that I can’t resolve on my own. What I need right now is straight-forward technical support with a strong focus on troubleshooting. The exact fault lines aren’t fully mapped yet—that’s why I’m turning to someone who’s comfortable methodically isolating problems, testing hypotheses, and guiding me to a clean resolution. Here’s how I picture the engagement: • You jump on a quick call or chat to gather environment details and replicate the failure. • We narrow down root causes together—whether the culprit ends up being code, configuration, network quirks, or even a hardware hiccup. • You document each fix or workaround as you go so I can re...

I need a thorough, methodical security assessment of my production-ready web application. The goal is to expose any weaknesses before launch, demonstrate real-world exploitability, and give me a clear, prioritized plan for remediation. Scope • Full application security testing: authentication, authorization logic, input validation, business-logic flows, session management, server configuration, and third-party integrations. • Black-box techniques are fine, but I can supply test credentials for deeper analysis if that helps you reach code paths hidden behind login. • Industry-standard tooling such as Burp Suite, OWASP ZAP, Nikto, or your preferred commercial scanner is expected, followed by manual verification so I’m not just getting automated false positives. ...

My iPhones and several smart-home devices have almost certainly been compromised. Unexplained behaviour, network slow-downs and repeated password lockouts suggest an active intrusion that I have not been able to stop remotely. I need an experienced cyber-security professional to visit in person, trace the breach and leave every device—and the Wi-Fi network itself—clean, secured and fully documented. What I expect during the visit • A thorough forensic check of each affected iPhone and the smart-home hub/gear, including router or mesh nodes you judge relevant. • Immediate containment and removal of any malicious profiles, apps, firmware or network configurations you uncover. • Clear advice on whether each device can be salvaged or should be replaced, follow...

A recently rebuilt Windows workstation needs a bullet-proof antivirus setup carried out over a remote session. The job begins with selecting an effective AV suite (I am open to your recommendation—Norton, McAfee, Kaspersky, or another best-in-class option) and continues through full installation, optimisation, and hardening. Key protection goals • Online banking: isolate browser sessions, enable real-time phishing & key-logger defences, and verify safe-transaction modules are active. • Confidential files: enforce on-access scanning, tune heuristic settings for maximum detection, and lock down local folders with password-protected vaults or encryption available within the AV. • Google Drive sync: ensure cloud-storage scanning is enabled, block malicious file ...

I run a production-level Windows server that now needs steady, professional care. The box is already up and live; what I need is someone who can step in and take over the routine work that keeps it healthy and secure. Your core responsibility will be ongoing maintenance—installing patches, checking logs, pruning obsolete services, and making sure performance never drifts. In parallel, I want proactive security updates: closing vulnerabilities quickly, hardening configurations, and documenting every change so there are no surprises later. A typical month might include: • Scheduling and applying Microsoft updates with minimal downtime • Reviewing Event Viewer and other logs for early warning signs • Updating firewall rules or IPS policies when new threats emerge ...

I’m building a Spring-based service router and need robust CSRF protection on all API endpoints. The idea is to leverage Public Key Infrastructure so that every incoming request carries a verifiable, signed token before it reaches any controller logic. Here’s the core of what I’m after: • A Spring Security configuration (Boot-compatible) that intercepts every request—GET, POST, anything—and checks a PKI-backed CSRF token. • A lightweight way for upstream services or clients to obtain and refresh that token; we can refine the flow together once you see my current architecture diagrams. • Server-side validation that ties the token to the session (or an equivalent stateless approach) so replay attacks are blocked. • Clean, readable ...

For this project I'm looking for a VERY competent consultant on Windows systems and (maybe) on ethical hacking. Standard approach is not useful and doesn't solve the task. I want to clarify that the request is made for purely educational and exercise purposes. The goal is to make a client accessible/usable again (ethical hacking techniques). The target client is really closed/blocked. The client is Windows 11 Enterprise 23H2 - Experience Pack 1000 - 64bit (OS build 22631.5908) Actual landscape: - Windows user is not local machine Administrator. - The local disk is encrypted via BitLocker (booting from the outside therefore does not allow reading the data); - BIOS has a password, not known; - Unauthorized applications are not allowed (no possible to install nothing more). - ...

I need an experienced Privileged Access Management engineer who can immediately take ownership of our Delinea Secret Server and Endpoint Privilege Manager landscape. Your first responsibility will be the daily care-and-feeding of the vault itself—credential onboarding, policy tuning, monitoring, and rapid troubleshooting—so that administrators, service accounts, and applications can continue to work without interruption. Beyond steady-state operations, I want you to drive the next wave of improvements that will make life easier for our users. The priority is clear: simplify access without diluting security. That means reviewing our current request workflows, tightening least-privilege rules, and automating as much of the approval and credential rotation process as possible whi...

I need a hands-on network engineer for a single day of onsite work.

I am conducting an authorised security assessment on a website that currently sits behind Cloudflare. The owner has given me written permission to verify how well the service hides the origin server, and my first objective is simple: locate the true, routable IP address of that server. What I need from you • Discover the origin IP without disrupting production traffic or triggering any Cloudflare security events. • Confirm that browsing directly to the uncovered IP renders the site identically to the public domain (same content, layout, and functionality). • Provide a concise report describing the exact approach—whether you relied on passive DNS enumeration (dig, SecurityTrails, Shodan etc.), historical records, sub-domain leakage, server misconfiguration, or ...

I’m looking for an experienced desktop-support professional who can step in and look after every aspect of my Windows machines. I run a mix of personal PCs and small-office workstations, so the environment shifts between home-use convenience and business-grade reliability.
