Helping fintech startups close enterprise deals and pass investor due diligence — without slowing your engineering team.

The stakes
One breach costs more than your entire security budget.
The average cost of a data breach reached $4.88 million in 2024.
(IBM Cost of a Data Breach Report, 2024)
Enterprise deals fall through
Investors and enterprise clients require SOC 2 before signing contracts. Without documented security proof, deals die in due diligence — regardless of your product quality.
Breaches destroy trust permanently
73% of consumers say they would stop doing business with a company after a data breach. The reputational damage outlasts the technical damage by years.
(Ping Identity Consumer Survey)
Compliance takes months without guidance
Most fintech startups spend 6 to 12 months achieving SOC 2 certification without expert help. We compress that timeline to 90 days without becoming a bottleneck for your team.

Our clients
Built for fintech startups moving fast.
You are six weeks from closing your Series A and investors just asked for your SOC 2 report. Your enterprise prospect sent a 40-question security questionnaire. Your CTO wants to know if your API is exploitable before you launch to 10,000 users.
That is exactly who we built Korvonex for.
We work with founders and engineering leads who are moving fast and cannot afford to let security become a growth bottleneck.
SOC 2 Type 1 certification can unlock enterprise contracts 10 to 50 times larger than your current deal size.

H. Muhammad Hassaan
Founder & Lead Security Engineer
Twelve years across fintech security, payment infrastructure, and SOC 2 audit preparation. Previously led security at two US fintech startups through successful Series A and B rounds.
Offensive security specialist with deep experience in web application, API, and cloud infrastructure testing. Has identified critical vulnerabilities in Fortune 500 payment systems.
Audit-focused practitioner who has guided fifteen fintech startups through SOC 2 Type 1 and Type 2 certification. Specializes in translating auditor expectations into engineering action items.
Series A fintech preparing to onboard enterprise payment clients. Security questionnaire from a Fortune 500 prospect blocked the deal. Internal team lacked bandwidth for a thorough security review.
Approach
Manual penetration test of the payment API and authentication layer, followed by an architecture review of the cloud infrastructure. Identified three critical vulnerabilities the previous automated scanner had missed.

Threat landscape
What attackers are targeting right now.
Threat trends observed across fintech engagements in 2024. We test against the current attack surface, not last year's checklist.
API authentication bypass
Attackers increasingly target weak API auth flows. Most fintech breaches in 2024 started here.
+34%
Critical
Business logic exploitation
Rate-limit bypass, race conditions, and flow manipulation. Scanners miss these entirely.
+28%

Third-party supply chain
Compromised dependencies and vendor APIs. Your security is now the sum of your integrations.
+22%

Credential stuffing
Still the most common attack vector, but MFA adoption has flattened its growth.

Legacy SQL injection
ORM adoption and parameterized queries have reduced this dramatically. Still appears in legacy code.

Why automated scanners are not enough
Automated vulnerability scanners catch the obvious. They miss business logic flaws, authentication bypass chains, and architectural vulnerabilities. Here is what manual testing finds that scanners cannot.

We hold ourselves to the same standards we hold you to.
Security is not just what we sell. It is how we operate. Here is exactly how we handle your data.
Data handling
How we handle your data
All engagement data is encrypted at rest (AES-256) and in transit (TLS 1.3). Stored in access-controlled systems with audit logging.
Encryption at rest: AES-256
Encryption in transit: TLS 1.3
Access logs retained for 90 days
Data deleted within 90 days of engagement end
Access control
Who can access your data
Only the assigned engagement lead and approved testers. Access is revoked within 24 hours of engagement completion. No offshore outsourcing.
Role-based access control (RBAC)
MFA required for all systems
Access revoked within 24 hours of engagement end
No third-party or offshore access
Confidentiality
Mutual NDAs and legal protection
We sign mutual NDAs before any technical work begins. Findings reports are confidential and never shared with third parties without written consent.
Mutual NDA before engagement start
Findings reports are client-owned
No data sharing with third parties
Attorney-client privilege available
Sub-processors
Our sub-processor list
We use a minimal set of vetted sub-processors. All are SOC 2 Type 2 certified. We notify clients 30 days before adding any new sub-processor.
Cloud hosting: AWS (SOC 2 Type 2)
Communications: Google Workspace (SOC 2 Type 2)
Version control: GitHub Enterprise (SOC 2 Type 2)

Security glossary
Speak the language of security.
Plain-English definitions for the terms your auditor, investor, and engineering team will use.
Compliance
SOC 2
Security framework developed by the AICPA. Type 1 evaluates control design at a point in time. Type 2 evaluates operating effectiveness over a period (typically 3–12 months). Required by most enterprise clients before signing contracts.
Testing
OWASP Top 10
The Open Web Application Security Project’s list of the ten most critical web application security risks. Updated periodically. The de facto baseline for web application penetration testing.
Testing
CVSS
Common Vulnerability Scoring System. A 0.0–10.0 score representing vulnerability severity. Critical (9.0+), High (7.0–8.9), Medium (4.0–6.9), Low (0.1–3.9). Used to prioritize remediation.
Testing
Penetration Testing
Authorized simulation of real-world attacks against a system to identify exploitable vulnerabilities. Manual testing by skilled engineers, distinct from automated vulnerability scanning.
Architecture
Attack Surface
The sum of all points where an attacker can attempt to enter or extract data. Includes APIs, web apps, mobile apps, cloud services, third-party integrations, and employee credentials.
Architecture
Threat Modeling
Structured process of identifying, quantifying, and addressing security risks to a system. Typically performed during architecture design, not after deployment.
Threats
Zero-Day
A vulnerability unknown to the vendor or for which no patch exists. Cannot be defended against by patching alone — requires defense-in-depth and behavioral detection.
Threats
Ransomware
Malicious software that encrypts files and demands payment for decryption. Modern variants also exfiltrate data and threaten public release ("double extortion").
Architecture
MFA
Multi-Factor Authentication. Requires two or more verification factors (something you know, have, or are). Reduces account takeover risk by 99.9% per Microsoft research.
Threats
SSRF
Server-Side Request Forgery. An attacker tricks a server into making requests to internal resources. Caused the 2019 Capital One breach (106M records exposed).
Testing
Business Logic
Application-specific functionality that automated scanners cannot test. Includes rate-limit bypass, race conditions, privilege escalation via workflow manipulation.
Testing
Remediation
The process of fixing identified vulnerabilities. Includes code changes, configuration updates, architecture modifications. Distinct from mitigation (reducing risk without fixing root cause).
