Inventory of all external presence
Starting from the root domain, CSURFACE maps applications, APIs, cloud environments, and assets related to units and brands — even what the official inventory does not register.
FINANCIAL SERVICES
External exposure under control in the financial sector.
Banks, fintechs, and payment institutions operate a broad and constantly changing digital surface—applications, open APIs, cloud environments, and an extensive partner ecosystem. CSURFACE discovers and continuously monitors this external exposure from the attacker's perspective.
THE CONTEXT
A growing attack surface faster than inventory growth
The financial sector is among the most targeted by attackers, and for good reason. Institutions handle sensitive data, maintain open integrations with third parties, and adopt technology at an accelerated pace. As regulated entities, they respond to BACEN Resolutions CMN nº 4.893/2021 and nº 4.557/2017, which require a cybersecurity policy and continuous risk management—including supplier risk management. Each new application, open finance API, or cloud environment provisioned expands the external attack surface, often without passing through the official security inventory.
The blind spots are known: forgotten assets from discontinued products, related units and brands outside the central inventory, accidentally exposed test environments, and reliance on a digital supply chain of suppliers that each institution does not directly control. The attacker enumerates all this. The security team must see the same.
HOW CSURFACE HELPS
Visibility applied to the financial sector reality
The platform discovers, categorizes, and prioritizes external exposure — with the context a financial institution needs to act.
Monitored open interfaces
The open interfaces that sustain the financial ecosystem are identified and continuously monitored as they change.
Prioritization by active exploitation
The queue reflects what is under observed exploitation — indicators of active exploitation and emerging threats — cross-referenced with the criticality of the channel: open finance, PIX, and transactional portals first.
Evidence for BACEN compliance
Each asset, finding, and change on the surface is recorded with an auditable trail — objective material to demonstrate due diligence in front of the CMN Resolutions nº 4.893 and nº 4.557, including supply chain risk.
| Asset | Type | Exposure |
|---|---|---|
| api-openfinance.exemplo.com.brOpen API | Open Finance | critical |
| pix.exemplo.com.br | Transactional portal | high |
| app-banking.exemplo.com | Mobile app/API | high |
| hml-core.exemplo.com.brHomologation | Forgotten environment | critical |
Each exposed channel — open finance, PIX, apps — enters the inventory with the business criticality context.
FREQUENTLY ASKED QUESTIONS
FAQ
Does CSURFACE need access to the institution's infrastructure?
No. Discovery is entirely external and only involves the root domain of the organization. We do not install agents nor require credentials or internal network access.
The platform operates autonomously. Optionally, CSURFACE integrates with cloud environments, WAFs, CIEMs, and other sources to enrich analysis — integrations that expand context but are not necessary for the platform to function.
Does the platform cover APIs and cloud environments?
Yes. APIs exposed on the internet and the external exposure of cloud environments are part of the discovery scope, just like web applications, certificates, and publicly accessible services.
Do findings support compliance with BACEN?
Yes. The platform maintains an auditable trail of each asset, finding, and change on the external surface, with history — objective material to support cybersecurity policies and risk management required by CMN Resolutions 4.893/2021 and 4.557/2017, including supplier risk monitoring. The same record supports compliance with LGPD in handling financial data.
