Web application testing
Exposed applications and portals are evaluated against the most relevant risk classes — including categories from OWASP Top 10.
AUTOMATED SECURITY TESTING
Security tests that accompany your surface.
CSURFACE performs automated security testing over the entire external attack surface of the organization. Active and passive verifications, conducted continuously and securely — without agents, without maintenance windows, and without asset lists to provide.
THE CHALLENGE
Piecemeal assessments age too quickly
The attack surface changes constantly: new applications are published, configurations are altered, dependencies are updated, and environments are provisioned. An assessment conducted at a single point in time reflects only the state of that day—and becomes invalid as soon as the environment evolves.
The interval between one assessment and the next is precisely the period during which flaws are introduced without any verification. To close this gap, security testing needs to keep pace with the surface it protects.
CAPABILITIES
Continuous testing of all external exposure
Permanent security verification on each discovered asset, at the rate that the surface changes.
API testing
Published API endpoints are verified for authorization, authentication, and data exposure failures.
Configuration verifications
Sensitive files exposed, unprotected administrative panels, default credentials, and insecure TLS configurations are identified.
Active and passive verifications
Passive analysis of observable signals combined with controlled active verification — to expand coverage without increasing risk.
Exploitability validation
Where active test coverage exists, the finding is evaluated for real-world exploitability in the context of the asset; elsewhere on the surface, evaluation is by passive detection.
Safe production operation
Tests are conducted non-destructively, designed to preserve the availability of the evaluated environments.
| Test | Asset | Result |
|---|---|---|
| Injection (SQLi / XSS) | api.exemplo.com | exploitable confirmed |
| TLS configuration | mail.exemplo.com.br | no finding |
| Exposed administrative panel | admin.exemplo.com.br | exploitable confirmed |
| Security headers | www.exemplo.com.br | partial |
Active, safe, and non-destructive tests confirm what is truly exploitable — the team addresses confirmed exposure.
VALIDATION
Validated findings where active testing coverage exists
Detecting a potential vulnerability is the simplest step. The important work is confirming whether that potential represents a real and actionable risk — or just noise that consumes team time.
The CSURFACE validates findings before presenting them, distinguishing what is exploitible from what is not. The result is a backlog of work that the security team can address with confidence, without needing to manually reconfirm each item.
CASCADE IMPACT
From an exploitable asset to the blast radius
When a test confirms an exploitable asset, the platform projects the reach through the connections: the assets directly connected to the compromised asset and subsequently those that depend on them—the blast radius, over the complete surface map.

- 5
Blast radius calculated and projected
Validation does not stop at the finding: it shows what is at risk. Prioritization now considers everything that its exploitation would reach.

HOW IT WORKS
From Discovery to Validated Findings
01
Discovery
The external attack surface is continuously mapped, defining the scope of assets to be tested.
02
Automated Testing
Each asset undergoes active and passive verifications, conducted continuously and securely for production.
03
Validation and Delivery
Findings are validated for exploitability and delivered with context, evidence, and prioritization.
WHAT YOU GET
Persistent coverage, without the operational cost of sporadic campaigns
Tests that monitor the surface reduce the time a flaw remains exposed before verification.
Continuous coverage
External exposure is reassessed continuously, at a constant cadence.
Less noise
Validated findings regarding exploitability are ready for treatment by the team.
Frictionless operation
No agents, no maintenance window, and no expected impact on the availability of environments.
FREQUENTLY ASKED QUESTIONS
FAQ
Do the tests require agents or access to the internal network?
No. The verifications are conducted externally, from the root domain of the organization. There are no agents to install nor infrastructure credentials to provide — 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 tests to function.
Can the tests affect the availability of environments?
The tests are designed to be non-destructive and safe for production. Active verifications use controlled techniques aimed at confirming the existence of a failure without compromising service.
What is the difference between active and passive verification?
PASSIVE verification analyzes observable signals from the asset without additional interaction. ACTIVE verification interacts with the asset in a controlled manner to confirm the presence of a failure. Both approaches are combined to increase coverage.
Do the tests replace a manual pentest?
They complement each other. Automated tests ensure continuous coverage of the entire external surface, while a manual pentest delves into specific scenarios. Together, they reduce the interval between evaluations.
