Internet Security Jobs

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’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...

My e-commerce site is currently under an active DDoS attack. No protective measures are in place yet, and service interruptions are starting to hurt sales and SEO. I have full administrative access to the Nginx server, so any configuration changes or security software installs can be done immediately. I need an experienced DDoS mitigation specialist to: • Restore site availability quickly by filtering malicious traffic and keeping legitimate customers online • Harden the existing Nginx stack with rate-limiting, connection throttling, and optimized firewall rules • Configure and fine-tune an external protection layer (e.g., Cloudflare, AWS Shield, or comparable scrubbing/WAF service) • Deliver a brief post-incident report outlining what was done, residual risks,...

I am ready to move straight into the Execution and Testing phase of ITSAR for a new telecom product and need a specialist who can see the process through to formal certification. Here is what the engagement will look like: • Hands-on execution of ITSAR security tests focused on the product’s network security stack and its software layer. You will be working directly on live units in a Linux-driven environment, so solid command of networking, penetration techniques, vulnerability assessment tools and telecom-grade hardening practices is essential. • Close coordination with NCCS and the relevant Telecom Security Test Labs (TSTLs). I will involve you in all technical calls and data exchanges; you will help interpret lab feedback, tweak test cases, and make sure every issue ...

I’m looking for a seasoned DevOps mind to streamline my GitHub-based CI/CD workflow and tighten the security of a handful of Linux servers. On the CI/CD side, everything lives in GitLab. I need practical guidance on structuring ., optimising runner usage, and setting up automated staging-to-production deployments with roll-backs and clear version tagging. If you have shortcuts for caching, parallel jobs, or environment-specific variables, even better. The servers behind those pipelines also need attention. Your job is to harden them—from SSH policies and firewall rules to OS-level patching and intrusion detection—so they’re production-ready once the pipeline pushes new code. Deliverables • A working, documented GitLab CI pipeline that builds, tests, and depl...

I’m assembling an intermediate-level cohort that needs a knowledgeable cybersecurity instructor to guide them through a series of live online classes. Each session must weave together the three focus areas the group has requested: • Network Security • Ethical Hacking • Cryptography My priority is real-time interaction, so please be comfortable running practical demonstrations, answering questions on the spot, and setting up hands-on labs that students can follow along with remotely. I will provide the video-conferencing platform; you bring the course structure, teaching materials, and technical expertise. Deliverables I need from you: 1. A clear syllabus that maps out how the topics will be covered over the duration of the course. 2. Slide decks or visual ai...
