Kester.
Security operations engineer with 3+ years in enterprise cloud/hybrid security. I build detection logic, respond to incidents, and automate away the boring stuff — all while making sure humans stay the strongest link, not the weakest.
The person behind the packets
I'm a cybersecurity engineer at a large dental equipment distribution company where I own security operations end-to-end: from SIEM tuning and incident response to phishing simulations and WDAC policy rollouts.
My experience with technology spans the full Microsoft security stack — Defender XDR, Sentinel, Purview DLP, Entra ID, and Intune — plus tools like Arctic Wolf, NinjaOne, AppTrana WAF, Barracuda WAF, Burpsuite Pro, and more.
Outside the SOC: I run Legacy Etch LLC, a laser engraving business, and Trust No Packet — a cybersecurity-themed blog and public education platform.
Based in Scranton/NEPA. Open to remote security roles.
Where I've worked
Built Benco's security awareness program from scratch — phishing simulations, KnowBe4-style campaigns, and "Phish Phriday" newsletters — reducing user click rates by 62% in six months. Tuned Sentinel analytics rules, and authored Purview DLP policies across Exchange, SharePoint, Teams, and endpoints. Also completed a responsible disclosure for a credential-storage vulnerability in a vendor desktop application.
Resolved 1,500+ tickets in 5 months — 500 in July 2023 alone. Maintained perfect QA scores and earned the QA AllStar Award. Administered Active Directory provisioning, Group Policy, DNS, VPN, and DHCP across a multi-site environment.
Maintained production IT uptime across scanners, printers, and workstations. Led root cause analysis on manufacturing defect data and coordinated with engineering to implement measurable process improvements.
Selected work
Engineered a three-scan Publisher/Hash strategy to build a supplemental WDAC policy in an enterprise environment — without breaking developer workflows.
↗Performed deep baseline analysis via AppTrana WAF. Identified a cart-polling bug skewing thresholds, whitelisted IPs, and prepared full stakeholder documentation for tuning decisions.
↗Built Benco's security awareness training from scratch. Designed phishing simulations, launched "Phish Phriday" campaigns, and reduced user click rates by 62% within six months.
↗Built a Chrome browser extension to detect and block ClickFix-style social engineering attacks — a technique that tricks users into pasting malicious commands. Built for personal and family use.
↗Founded and operate a laser engraving business selling personalized gifts and memorial items. Handles full e-commerce stack — product, fulfillment, and marketing.
↗Cybersecurity-themed blog and public education platform. Detection notes, threat research, and security engineering write-ups.
↗Network security visualizer
