Summary
👤
Senior🎓
Top SchoolPeter Scheffler is a Cyber Security Solutions Architect with nine years at F5 Networks and a decades-long career turning complex security problems into practical, deployable architectures for the Global 1000. He specializes in API and application security, identity federation, zero trust design, and pragmatic adoption of emerging crypto (including hands-on work with post-quantum TLS). A proven field engineer and sales technologist, he builds PoCs, trains partners, and coaches engineers through CTF-style exercises to shift teams from reactive to attack-informed defense. He partners with product teams to translate customer needs into new solutions and has a track record of increasing WAF and app-sec adoption across regions. Outside the job he blends creative problem-solving with a dry sense of humor—writing, mentoring, camping, and even designing RPG characters—bringing a human angle to technical leadership. Based in Old Toronto, he’s especially worth talking to if you’re wrestling with API security, LLM risk, or mysterious mTLS breakages.
