Digital supply chain at the code level
Third-party scripts, analytics tags, CDNs, and runtime-embedded libraries in your applications. CSURFACE maps each dependency and the exact observed version — before the next compromise turns into an incident.
CONTINUOUS EXPOSURE MANAGEMENT
Continuous proof
of your external exposure
Supervision stopped accepting the annual snapshot and started asking for a living record. CSURFACE audits the coverage of the scanner the institution already pays for, shows what answers on the internet outside the inventory, and proves what is exploitable from outside, with the evidence the target itself returns.

the oldest exposed vulnerability we have ever found
In 2 out of 3 analyzed companies, there is an exploitable vulnerability forgotten for more than five years. In over half of them, with public exploit code available.
The gap lies in knowing what exists before any security tool can help. See the full panorama in State of Digital Exposure →
WHY THIS MATTERS
The attacker only needs one opportunity: the path of least resistance.
Usually, it's an asset absent from the inventory — exposed and out of any control. The three most common gaps we find:
1,068related organizations and environments outside the inventory
Forgotten subdomains and environments
Homologation portals, discontinued environments, and forgotten subdomains remain published and without security updates — a low-visibility vector of entry that can be exploited without generating any alert in the operation.
37%of the analyzed companies had leaked corporate credentials
Leaked corporate credentials
Credentials appear in public breaches and on the dark web. Detection takes, on average, 94 days — a window sufficient for credential stuffing attacks against the organization's portals.
71%of the exposed web applications operate without WAF
Shadow IT and unauthorized SaaS
Business areas contract tools, provision cloud environments, and publish APIs without going through security. Assets outside the inventory fall out of the scope of protection and compliance audits.
In more than a third of data breaches, there was shadow data involved — information in unmanaged assets, out of the security radar.

WHY CSURFACE
CSURFACE operates at the pace of threat, in a continuous cycle.
Machine Learning and the agentic layer reevaluate the surface continuously, every few hours. They attribute the property of each asset and, where there is test coverage, confirm exploitability before the alert reaches the team.
- Single platform: discovery, validation, and prioritization in one continuous cycle
- Discovery of shadow IT and assets outside the official inventory
- Mapping of digital supplier chains at the code level
- Continuous monitoring of leaked corporate credentials
- Validation of real exploitability, beyond static CVSS
COVERAGE TEST
How many assets does your organization not know it has?
In recent clients, CSURFACE discovered up to 6.7× more assets than the official inventory reported. These are real deployment numbers with defined client and scope.
Financial institution · medium size+69% · 1.7×
The organization operated with 160 external assets. CSURFACE delivered 271 — inherited subdomains, forgotten environments, and services published that were not in any CMDB.
B2B SaaS startup · Brazil+571% · 6.7×
Engineering monitored 85 assets. CSURFACE discovered 570 — environments provisioned without security review, inherited services from previous phases, APIs published outside formal process.
Real cases, anonymized identifiers. Metric: external assets not listed in the client's official inventory, attributed with confidence ≥ 95% by the agentic layer.
CONTINUOUS MONITORING
Between a scheduled scan and the next, an exposure window opens.
Scheduled scanning tools—monthly or weekly—only see the surface at the moment of execution. A new published asset, a critical CVE disclosure, an expired certificate, or a leaked credential between one scan and the next remain invisible until the subsequent scan. CSURFACE continuously monitors and closes this gap.

From discovery to mobilization, without interruption.
Seven chained steps that the platform executes and re-executes in a loop — keeping the inventory alive and the risk queue always in the present of the threat.

Each alert answers three questions:
is it yours, is it exploitable, is it worth acting on.
THE PLATFORM IN PILLARS
A platform, all pillars of exposure management
The report is the entry point; the platform keeps you ahead. Discovery, prioritization, validation, and response operate under a single data model — each pillar feeds the next.
Phase 1 · Discover
The entire surface area
Map everything that is exposed, seen from the outside.
Phase 2 · Prioritize
What matters first
Focus on what is actually exploitable and critical.
Phase 3 · Validate & respond
Prove and act
Confirm what is real and close the attack path.
DIGITAL SUPPLY CHAIN
Your attack surface includes what you don't control.
Each external dependency — embedded scripts, CDN, consumed APIs, contracted SaaS — enters your attack surface through its own domain. When the third party is compromised, the attack reaches your HTML without the attacker touching your infrastructure. This was exactly how the Polyfill.io incident in June 2024 affected over 100,000 legitimate websites.
Dependent APIs and endpoints
Third-party endpoints your product consumes, exposed keys in frontend, OAuth scopes granted. When the provider fails or is compromised, the impact falls on your customer, through your own environment.
External posture of suppliers
A discipline separate from the embedded code chain: third-party assessment looks at the observable external posture of each critical supplier — payment, identity, messaging, ERP. It's what the attacker sees from the partner before the attack reaches the supply chain.
NATIVE INTEGRATIONS
Connected to what already runs in your operation.
CSURFACE connects natively to the stack that your team already uses — SIEM, ticketing, ChatOps, SOAR — so the validated alert reaches the existing workflow within the same environment that the team regularly consults.

WHAT CUSTOMERS SAY ABOUT US
What security customers say about CSURFACE.
Rodrigo · Cybersecurity Manager · One of Brazil's largest startups
I haven't seen any other platform offering what CSURFACE is offering.
Joel M. · Cybersecurity Specialist · A large financial company
A unique approach compared to the various ASM products currently available in the market, projecting a significant reduction in false positives and being assertive in indicating prioritization of vulnerabilities that make sense.
Rodrigo · Cybersecurity Coordinator · One of Brazil's largest companies
CSURFACE allowed us to discover that we were monitoring only 15% of our actual attack surface. There was a chronic visibility problem, with legacy assets that could become serious incidents at any moment.
Guilherme C. · Security Manager · Multinational
The platform enabled benchmarking against market standards, especially in potential financial impact, and helped us detect issues with a higher probability of becoming incidents.
FREQUENTLY ASKED QUESTIONS
FAQ
Is the preliminary analysis really free?
Yes. You provide a corporate email and receive, in your email, a preliminary report with the main findings of your company's attack surface. No credit card required, no mandatory meeting, and no commercial engagement.
Why do I need to use a corporate email?
The analysis runs on the domain of your email. That's why we don't accept free providers (Gmail, Hotmail, Outlook, etc.) — and that's why we ask you to confirm ownership or authorization over those assets.
How long does it take to receive the report?
We email you as soon as the report is ready. There is no fixed deadline, because it depends on how many assets discovery finds on your domain. The analysis is performed externally — we don't depend on installation or access to your infrastructure.
Is the analysis intrusive? Do you need access to my network?
No. The preliminary analysis is — based on external observation and public sources, exactly from an attacker's perspective. No agents, no installation, no destructive testing. See the Preliminary Analysis Terms.
What does CSURFACE find that my team doesn't see?
Subdomains and forgotten environments, shadow IT, assets outside the official inventory, leaked corporate credentials, and the digital supply chain embedded in your code. It's common for a company to discover multiples of additional assets beyond its official inventory.
How does CSURFACE differ from Tenable and Qualys?
A unique platform that goes beyond asset inventory: discovery with Machine Learning of shadow IT and assets outside the inventory, mapping of the digital supply chain of suppliers, monitoring of leaked credentials, and validation of exploitability. See the platform differences.
