Our Origin
The Story Behind Sentiplug
Born out of frustration and necessity, Sentiplug's founding team spent years in enterprise security — and then watched small businesses get devastated by the same attacks with zero defenses.
In 2019, our co-founders Khandaker Zaman and Rakeybul Hasan were working as senior security engineers at a major cloud provider when a close friend's e-commerce business was wiped out overnight — not by a sophisticated nation-state actor, but by an automated bot exploiting an unpatched plugin vulnerability. The business lost six months of customer data and never fully recovered.
That incident was the catalyst. They both resigned within the same week and started building from a garage in Germantown, Maryland. The goal was singular: take the enterprise-grade firewall and threat intelligence that only Fortune 500 companies could afford, and make it accessible to every website owner on earth — for free if necessary.
The first version of Sentiplug was a 900-line PHP script shared in a WordPress developer forum. Within three months, it had been downloaded 40,000 times. They knew they were onto something real.
By 2021, the team had grown to 12 engineers, launched a cloud-based threat intelligence network, and secured seed funding from leading cybersecurity VCs. Today, Sentiplug protects over 500,000 active websites across WordPress, WooCommerce, and custom web frameworks — blocking more than 4.9 million threats every single day.
We remain headquartered in Maryland, with engineering offices in Austin, London, and Singapore. We are and always will be a security-first company — not an ad platform, not a data broker, not a growth-hacking machine. Just tools that keep websites safe and owners sleeping soundly.
