Scales of discovery
Starting from the root domain, CSURFACE maps IP ranges, edge devices, portals, and APIs exposed — including assets from units and brands acquired that escape central control.
TELECOMMUNICATIONS
Cybersecurity for operators and providers.
The telecommunications sector operates one of the largest and most distributed attack surfaces that exist. CSURFACE discovers, classifies, and continuously monitors the assets of operators and providers exposed on the internet — including those not registered in any inventory.
THE SECTOR CONTEXT
A vast, distributed, and constantly changing attack surface
Operators and providers manage extensive address ranges, thousands of edge devices — gateways, routers, and CPEs installed at the customer end —, self-service portals, business systems, and a web of integrations with partners. As regulated service providers under the Lei Geral de Telecomunicações by Anatel, they are responsible not only for operational continuity but also for protecting subscriber data under LGPD. Each element exposed on the internet is a potential entry point, making manual inventory management impractical.
Edge devices concentrate a significant portion of the risk: distributed in the thousands and often not updated at an adequate pace, they remain accessible via the internet 24/7. Added to this are the legacy of acquisitions and the units and brands incorporated over time — large blocks of IP addresses, domains, and environments that rarely achieve a unified view. It is this dispersed exposure that an attacker enumerates first.
HOW CSURFACE HELPS
Continuous visibility over a surface that never stops changing
The platform maps the external exposure from operators and providers from an attacker's perspective — without agents and without touching the network infrastructure.
Focus on the edge
Network elements and gateways accessible via the internet are identified and evaluated, bringing to visibility the layer that concentrates the most exposure in the sector.
Scales of prioritization
Among tens of thousands of assets, the queue highlights the few actively under exploration that truly matter — network elements and subscriber portals in front.
Subscriber data and compliance
Self-service portals and systems that custodiate subscriber data are highlighted in the inventory, supporting the protection required by LGPD and the due diligence expected from a regulated service under Anatel and classified as critical infrastructure.
| Asset | Type | Exposure |
|---|---|---|
| gw-edge.exemplo.com.brthousands at the edge | Edge device | critical |
| subscriber-portal.exemplo.com | Subscriber portal | high |
| 200.18.x.0/22IP range block | Addressing range | high |
| legacy-cpe.exemplo.com.brno updates | Exposed CPE | critical |
The vast and distributed surface — IP ranges, edge devices, and subscriber portals — consolidated in a single inventory.
FREQUENTLY ASKED QUESTIONS
FAQ
Does CSURFACE touch the network infrastructure of the operator?
No. The discovery is entirely external and only involves the root domain. We do not install agents nor require network access, making its adoption safe even in mission-critical environments.
The platform operates autonomously. Optionally, CSURFACE integrates with cloud environments, WAF, CIEM, and other sources to enrich analysis—integrations that expand context but are not necessary for the platform to function.
Does the platform identify exposed edge devices?
Yes. Gateways, routers, and network elements accessible via the internet are discovered and classified, bringing visibility to a layer that typically remains outside traditional inventories.
Does the platform cover large blocks of IP addresses?
Yes. Extensive IP blocks are enumerated and correlated with the root domain and operational units and brands, consolidating what typically spans multiple control systems into a single inventory—without relying on manually maintained lists.
