Scrubbing capacity
Security, delivered as one portfolio.
Because Dollu already operates the network your traffic crosses, we can secure it closer to the source: scrub volumetric attacks at the backbone edge, enforce Zero Trust policy at the PoP, and feed network telemetry directly into our SOC.
Our security services are managed end-to-end - from architecture and policy design to 24×7 monitoring, response and reporting - and are built for telecom, BFSI, BPO and SaaS environments where uptime and compliance are non-negotiable.
We also protect what is uniquely telecom: SIP trunks against toll fraud, SMS routes against grey-route abuse, and signalling against SS7/Diameter exploitation.
Everything in Security.
Each service has its own detailed page - overview, capabilities, onboarding, use cases, specifications and FAQs.
