From Oxford to Fiverr Pro: Denis's Cybersecurity Journey

Denis’s Fiverr ProfileEarly Passion for TechQ: Denis, how did your journey in cybersecurity begin?Denis: My interest started when I was a teenager in the 90s. I was programming in BASIC, Turbo Pascal, and Visual Basic on Windows 3.1 and 95. I fixed computers at school, sometimes better than my computer science teacher. I even created some automated test systems for teachers to save grading time. That was my first exposure to practical IT.Breaking into CybersecurityQ: How did you transition into cybersecurity professionally?Denis: Around 2005, I started working with banks like HSBC, Barclays, and Lloyds as a security engineer. I was securing ATMs, implementing cryptography, and hardening systems. It was the early stage of what we now call cybersecurity.The Oxford DreamQ: What inspired you to study at Oxford?Denis: As a child, I saw the word "Oxford" in science books at home. My grandmother was a paleontologist, and we had many academic books around. That name stayed with me. Years later, after building experience and earning certifications, I applied and was admitted to Oxford for a master’s in Software and System Security.Was Oxford Worth It?Q: Looking back, was it the right decision?Denis: Definitely. It took five years to complete while working, running a company, and raising two children. I passed my CISSP after failing once, got my ISO 27001 Lead Auditor certification, and later added CRISC and CISM. Oxford was tough, but it helped me level up my career.Working with Big Banks & Launching His CompanyQ: What was it like working with major corporations?Denis: I worked with seven international banks. At Fujitsu, I was a Principal Security Solutions Architect, reporting to the CISO and signing off on multi-million-pound security solutions. But the pressure was huge. Even while skiing in the Alps, I had to take work calls. That’s why I eventually launched my own limited company—to gain flexibility and balance.Discovering FiverrQ: With all that experience, why try Fiverr?Denis: I had known about Fiverr through a friend but only gave it a serious look in late 2024. Initially, I thought it was not for me, but then I started analyzing the platform. I spent two months watching videos—especially yours—and created around 17 gigs covering different cybersecurity services.First Sales and Niche FocusQ: How did your Fiverr sales begin?Denis: Real traction started in January 2025 after polishing my gigs for a few months. My services cover everything from GDPR to ISO 27001, PCI-DSS, and risk management. Because I worked across many domains in my career, I could confidently offer consultations in all of them.Gig Structure & PricingQ: How do you structure your offers?Denis: Most gigs are one-hour consultations with three tiers:* Basic: Delivery within 30 days* Standard: Delivery within 5 business days* Premium: Delivery within 2 days for urgent casesIn some cases, clients book multiple hours or even larger bundles. I am also preparing to launch subscription-based services for companies that need ongoing support but cannot afford a full-time Chief Information Security Officer.Pro Seller & Top Rated StatusQ: How did you become a Fiverr Pro and Top Rated Seller so fast?Denis: I applied for Pro Seller status shortly after joining. I had all the credentials—Oxford, industry certs, real-world experience—and got approved in about a month. I hit Top Rated Seller status within three months of consistent sales, maintaining a 100% response rate and success score of 10.Fiverr Project InsightsQ: What kind of clients and requests do you get on Fiverr?Denis: Most clients are small businesses, though I have worked with billion-dollar companies through Fiverr too. Some requests are strange—people asking me to hack systems or recover stolen accounts. I report those immediately. But overall, the platform has allowed me to serve a wide range of serious clients.Tips, Tools & WorkflowQ: Do you use any tools or have a team helping you?Denis: I work closely with a trusted colleague—one of the top technical cybersecurity specialists I know. He helps with the more technical engagements.
