Network & Security Engineer at Connex Information Technologies Limited implementing Darktrace NDR and Imperva WAF solutions.

Sri Lanka
Message

At Connex Information Technologies Limited, I work across deployment and L2/L3 support for cybersecurity products including Darktrace, Imperva WAF, and A10 Networks. I also help design multi-product solutions and support projects from planning through post-installation.

I designed and implemented an Imperva WAF deployment for a non-banking financial institution in Sri Lanka, onboarding more than 20 web applications. My work included solution design and implementation.

For a public bank in Sri Lanka, I implemented a Darktrace network detection and response solution with a dedicated dashboard for SOC teams to investigate and triage incidents. I also supported network integrations, model tuning, and customer training.

I implemented Darktrace for a multinational company in Bangladesh, configuring the deployment, integrations, and remote vSensors. I continue to provide L2 support for ongoing cases, and I hold certifications across Imperva, Qualys, A10, and other cybersecurity vendors.
