FinTech Mid-Market: Critical Vulnerability Missed by Multiple Security Tools

Their application was well protected and they had been using multiple security tools. They half-heartedly accepted Preservers scanning. Preservers identified a critical vulnerability that could be exploited with botnets.

FinServe (anonymized)February 1, 2025

Key Outcome

Discovered a critical botnet-exploitable vulnerability that multiple existing security tools had missed.

Critical vulnerability found
Botnet exploit path identified
Remediated before exploitation

A mid-market FinTech had invested heavily in security. Their application was well protected. They used multiple security tools and felt confident in their posture. When Preservers offered to run a scan, they agreed half-heartedly, expecting nothing new.

The Challenge

Their existing tools had given them a false sense of security. Firewalls, WAFs, and endpoint protection were in place. Penetration tests had passed. Yet something was missing. They had no visibility into attack paths that could be automated and scaled by botnets.

The Solution

Preservers ran a comprehensive scan of their external attack surface. The platform analyzed their assets, APIs, and entry points from an attacker's perspective. Within days, Preservers identified a critical vulnerability that could be exploited at scale using botnets. The finding had been invisible to their other tools.

The Results

The FinTech remediated the vulnerability before it could be exploited. They realized that multiple security tools were not enough without visibility into how attackers could automate and scale an attack. They now use Preservers as a critical layer in their defense.

Preservers: Attack Surface Management, Vendor Monitoring & Fraud Protection

From Reactive Security to Continuous Defense

External defense for platform and partner-heavy teams. Preservers helps platform businesses, payment operators, MSSPs, and security partners find shadow APIs, monitor vendor exposure, pass security reviews, and stop payment fraud before funds move or a deal stalls.

Why Engineering and Security Leaders Choose Preservers

External Attack Surface Visibility: Continuously discover exposed APIs, staging environments, and shadow assets the way an attacker sees your organization.
Vendor and Partner Monitoring: Watch the internet-facing exposure of processors, integration partners, carriers, 3PLs, and SaaS dependencies so their weakness does not become your breach.
Customer Trust Proof: Track compliance evidence for SOC 2, ISO 27001, and enterprise security questionnaires without a last-minute scramble.
Payment and Instruction Fraud Prevention: Detect scams and stop payment and vendor hijacking before a fraudulent transaction is approved.
Disruption-Free Security: Deploy without a massive IT overhaul and protect continuously.

Core Platform Offerings

Evaluating Attack Surface and Vendor Monitoring Tools

Common questions from platform, payment, and security teams researching external attack surface management, vendor risk monitoring, and security posture visibility.

What is external attack surface management (EASM)?: External attack surface management (EASM) is continuous discovery and monitoring of every internet-facing asset tied to your organization: domains, subdomains, cloud storage, forgotten portals, staging environments, and look-alike domains. Unlike a one-time scan or a letter-grade rating, EASM watches the perimeter as it changes. Preservers Preserve Surface provides EASM for SaaS and logistics tech teams that need to see exposure the way an attacker does, not only what is already on an asset inventory.
How is continuous attack surface monitoring different from a security rating?: A security rating summarizes historical signals into a score, often updated periodically and oriented toward boards, insurers, or large vendor programs. Continuous attack surface monitoring finds new exposures as they appear: a misconfigured bucket, a fresh look-alike domain, an exposed API in staging. Preservers focuses on operational visibility and remediation context through Preserve Surface and Preserve Connect, so engineering and security teams can act before an exposure becomes an incident or a lost deal.
What tools help monitor vendor and third-party exposure continuously?: Teams evaluating vendor risk typically choose between periodic questionnaires, rating feeds, or continuous external monitoring. Questionnaires go stale quickly. Ratings summarize but may not show a specific new subdomain or certificate lapse at a partner. Preserve Connect maps and monitors the internet-facing footprint of vendors, carriers, integration partners, and SaaS dependencies so you see third-party exposure change in near real time, not only at renewal season.
How can a growing SaaS company monitor cyber risk without a full enterprise GRC program?: Most Series A through growth-stage SaaS companies do not need a multi-year GRC rollout to improve visibility. Start with continuous external discovery of your own surface (Preserve Surface), extend monitoring to critical vendors and integration partners (Preserve Connect), and organize evidence for SOC 2 and customer security reviews (Preserve Compliance). Preservers deploys in under twenty minutes without DNS changes or a heavy IT project, which fits lean security teams that need outcomes, not another dashboard shelf.
What should a SaaS company look for in external security monitoring?: SaaS teams should prioritize tools that discover shadow APIs and staging environments, detect look-alike domains targeting customers, monitor integration partner exposure, and produce evidence for SOC 2 and enterprise security questionnaires. Preserve Surface finds external blind spots. Preserve Connect watches vendor and partner attack surface. Preserve Compliance organizes proof for customer trust centers and RFP responses. Together they address the workflows ratings-only tools typically do not cover.
How do logistics tech companies monitor vendor and carrier exposure?: Logistics platforms depend on carriers, 3PLs, TMS integrations, and payment partners, each with its own internet-facing footprint. Periodic assessments miss new portals, certificate lapses, and impersonation domains targeting freight payments. Preserve Connect monitors those partners continuously. Preserve Surface covers your own platform exposure. Preserve Fraud adds instruction-level protection when payment or routing details are changed by email.
What is the difference between attack surface management and vulnerability scanning?: Vulnerability scanning tests known assets for known flaws on a schedule you define. Attack surface management first discovers assets you may not know exist, then prioritizes what is actually exposed to the public internet. Preservers combines discovery, look-alike domain detection, certificate and blacklist awareness, and business-context prioritization so teams fix what matters to product and operations, not every CVE in a spreadsheet.
Who is Preservers designed for when evaluating security visibility platforms?: Preservers is built for SaaS and logistics tech companies that need continuous external visibility, vendor monitoring, and operational defense without a massive security team. If you are researching attack surface management, vendor risk monitoring, or security posture tools for a platform that moves data, payments, or shipments through partners, Preservers is designed for that buying context.
