Attack surface management for financial services
When you move money and hold customer financial data, you are a high-value target, and the attacks usually start at the edge: a spoofable domain, a forgotten portal, an exposed API. Resensor maps your internet-facing footprint continuously and ranks what is exploitable with CISA KEV and FIRST EPSS, so you close the gaps that lead to fraud and breaches.
The edge is where financial attacks begin
Customer portals, partner APIs, and your own brand are all attack surface, and the highest-impact exposures are rarely the ones on the asset list.
Spoofable domains fund wire fraud
If your domain lacks enforced SPF, DKIM, and DMARC, attackers send convincing payment emails as you. Business email compromise is the most expensive fraud category for a reason.
Look-alike domains phish your customers
Typosquatted domains impersonate your brand to harvest credentials and reroute payments. You need to know they exist before your customers fall for them.
Portals and APIs sprawl
Every customer login, partner integration, and acquired product adds public endpoints. One expired certificate or exposed service is a foothold.
Regulators expect proof
GLBA, the FTC Safeguards Rule, and PCI DSS all expect ongoing monitoring of the systems that hold customer data. You have to show the work.
What Resensor watches for financial firms
- Customer portals, APIs, and subdomains across your brands
- Email spoofability across SPF, DKIM, and DMARC posture DMARC
- Typosquatted look-alike domains built to defraud customers LOOKALIKE
- Expiring or weak TLS certificates on public systems TLS
- Unexpected exposed services and ports on the perimeter
- Known-exploited vulnerabilities from CISA KEV and high-EPSS CVEs KEV EPSS
- Employee credentials surfaced in known breach data BREACH
- Assets from acquired products discovered automatically
Evidence for GLBA, the Safeguards Rule, and PCI
The FTC Safeguards Rule expects a written information security program with ongoing monitoring and risk assessment of the systems that hold customer information, and you cannot monitor what you have not inventoried. Resensor keeps a current map of your internet-facing systems and their exposures, and every finding maps to SOC 2, ISO 27001:2022, and PCI DSS v4.0 controls, so a scan becomes audit-ready evidence rather than another spreadsheet.

What is attack surface management for financial services?
It is the continuous discovery and monitoring of every internet-facing asset a financial services or fintech firm runs, including customer portals, APIs, subdomains, and certificates, plus the domain and email exposures that drive fraud, so you can fix what an attacker could reach before they do.
How does attack surface management support GLBA and the FTC Safeguards Rule?
The FTC Safeguards Rule requires a written information security program with ongoing monitoring and risk assessment of the systems that hold customer information. External attack surface management keeps a current inventory of your internet-facing systems and their exposures, which supports that program. Resensor findings also map to SOC 2, ISO 27001:2022, and PCI DSS v4.0 controls.
How does EASM reduce wire fraud and business email compromise?
Most wire fraud starts with an impersonated domain. Resensor checks whether your domain can be spoofed by inspecting SPF, DKIM, and DMARC posture, and it surfaces typosquatted look-alike domains registered to phish your customers and staff, so you can close the gaps attackers use for business email compromise.
How does Resensor decide what to fix first?
Resensor ranks findings with CISA KEV (known exploited vulnerabilities) and FIRST EPSS (exploit prediction), so your team works the exposures attackers are actively using rather than a long list sorted only by CVSS severity.
