Cloud, security, and compliance for the SEC- and PCI-regulated end of fintech.

What fintech founders bring to us.

Pre-funding IT audit

Tech due-diligence prep. Get to a yes faster from your VC's technical advisor.

Payment-flow security

PCI-DSS, tokenization, secrets management, segregation of duties.

Cloud architecture

Multi-region, multi-AZ, RPO / RTO targets that survive a real outage.

What is at risk

In fintech, security is the product as much as the feature you shipped.

You move money and hold sensitive financial data, which puts you in the crosshairs of attackers and regulators at the same time. The pressure to ship fast is real, but a single payment or API breach can vaporize customer trust, freeze a partnership, and stall a funding round. The threats scale up exactly as you do.

Payment and API security - exposed keys, broken authorization, and unvalidated endpoints are the most common path to fraud and data theft in fintech.
Customer financial data - account, KYC, and transaction data that carries heavy compliance obligations and a high price if it leaks.
Compliance gaps - missing PCI-DSS, SOC 2, or ISO 27001 controls block enterprise deals, banking partnerships, and certain markets outright.
Diligence risk - investors and acquirers run technical due diligence, and unaddressed security debt becomes a discount or a dealbreaker.
Scaling pressure - architecture and access controls that worked at ten people quietly become the breach you suffer at a hundred.

How we secure fintech

Security that satisfies auditors, partners, and your own velocity.

We help you build security in rather than bolt it on, so the controls that protect customers are the same ones that clear diligence and unlock partnerships.

Payment and API hardening

Tokenization, strong authentication and authorization on every endpoint, secrets management, rate limiting, and segregation of duties around the money-movement paths.

Compliance and certification

PCI-DSS, SOC 2, and ISO 27001 readiness - gap analysis, control implementation, and evidence so you reach the SOC 2 report, ISO 27001 certificate, or PCI attestation a deal depends on.

Cloud and architecture

Multi-region, multi-AZ design with RPO and RTO targets that survive a real outage, plus infrastructure-as-code and hardened baselines that scale with you.

Identity and access

MFA, least-privilege, and clean separation between production and everything else - so a single compromised laptop cannot reach customer funds.

Monitoring and detection

Logging and a SIEM tuned to your stack that surfaces anomalous API use, suspicious transactions, and intrusion signatures while there is still time to act.

Pre-funding diligence prep

We get your security story, documentation, and controls into the shape a VC technical advisor or acquirer expects - so diligence accelerates the deal instead of stalling it.

How an engagement works

From a fast assessment to a posture that clears your next diligence call.

Assess

We review your payment flows, APIs, cloud architecture, and access model, then rank the gaps by fraud, breach, and deal-blocking impact rather than by checklist order.

Prioritize

A pragmatic roadmap that fixes the highest-risk and most deal-relevant items first, scoped to a startup budget and a shipping schedule you can keep.

Implement

We harden the payment and API layers, tighten cloud and identity controls, and stand up monitoring - working with your engineers so security lands without halting the roadmap.

Sustain

Ongoing monitoring, certification upkeep, and diligence-ready documentation so your posture keeps pace as you scale and as the next round or partnership arrives.

VAPT for fintech

What penetration testing a payment stack actually involves.

Testing a fintech is not testing a marketing site with a login. The money path, the ledger and the partner integrations each fail differently, and a generic web-app pentest misses all three.

The payment path end to end

Checkout, tokenisation, the PSP callback, the webhook handler and the reconciliation job. Webhook endpoints that accept unsigned callbacks, and replayable payment confirmations, are among the most common serious findings in this sector because they sit outside the part everyone remembers to test.

Broken object-level authorisation

The single most damaging class of bug in fintech APIs: an authenticated user reading or moving another customer’s money by changing an identifier. Scanners do not find it because every request returns 200. It needs a tester with two accounts and a hypothesis.

Ledger and balance integrity

Race conditions on transfer, double-spend through concurrent requests, rounding and currency-conversion drift, and negative-amount handling. These are business-logic failures and they are found by reasoning about the domain, not by fuzzing.

KYC and document handling

Identity documents are the highest-value data you hold after card numbers. Where they are stored, who can enumerate them, whether the upload endpoint validates content type, and whether presigned URLs expire.

Partner and sponsor-bank integrations

Mutual TLS configuration, credential rotation, IP allow-listing, and what happens to queued transactions when the partner is unavailable. Your security review will be judged partly on how you treat their connection.

Secrets and key management

API keys in client bundles, long-lived credentials in CI, keys that have never rotated, and encryption keys stored beside the data they protect. Consistently the fastest path from a minor foothold to a serious incident.

Diligence and partner reviews

The security questionnaire that is holding up your deal.

Most fintechs first contact a security firm because something is blocked - a sponsor bank, an enterprise customer, or an investor's technical diligence. Each asks for different evidence.

Enterprise customer reviews

A long questionnaire, usually SIG-Lite or a bespoke spreadsheet, plus a request for a recent pentest report. The pentest is the artefact that unblocks it; the questionnaire is answerable in a day once someone owns it.

Sponsor bank and PSP onboarding

More prescriptive: named controls, evidence of testing cadence, incident response contacts, and often an expectation of annual testing. They are managing their own regulator, so vague answers get returned rather than accepted.

Investor technical diligence

Focused on whether security debt will become a cost after the round. A ranked risk register with owners and dates does more here than a clean report does, because it demonstrates the function exists rather than that one test passed.

What actually unblocks each one

A current pentest report, a written risk register, evidence that findings get closed, and a named person accountable for security. That last one is why fintechs at this stage often want a vCISO retainer rather than a one-off test.

Fintech security FAQ

We are early stage and moving fast. Is security worth it now?

Yes, because the cheapest time to build security in is before the breach and before the diligence call. You do not need an enterprise program on day one - you need the high-leverage controls around payments, APIs, secrets, and access in place, and a clear path to the certifications your next deals will require. Done early, it accelerates you; done late, it becomes expensive rework or a lost deal.

Do we really need SOC 2 or PCI-DSS yet?

It depends on who you sell to and how you move money. Enterprise customers and banking partners increasingly require SOC 2, and handling card data brings PCI-DSS into scope. We help you figure out which frameworks genuinely apply, when, and get you ready efficiently rather than chasing certifications you do not yet need.

Can you help us pass technical due diligence?

Yes - it is one of the most common reasons fintech founders call us. We get your architecture, controls, and documentation into the shape investors and acquirers expect, fix the issues a sharp technical advisor would flag, and prepare you to answer their questions with evidence. The aim is for diligence to build confidence in the deal rather than slow it down.

Will security work slow our engineering team down?

We design it not to. We integrate controls into your existing pipeline, automate what we can, and prioritize so engineers fix the things that matter most rather than drowning in a generic checklist. Good fintech security removes future firefighting, which is what actually slows teams down.

How do you secure our payment and API layer specifically?

We start by mapping every path that touches money or sensitive data, then enforce strong authentication and authorization, tokenize sensitive values, lock down secrets, add rate limiting and anomaly detection, and separate duties so no single component or person has unchecked control. Then we monitor those paths continuously for abuse.

What makes VITI a good security partner for a fintech company?

We work specifically with regulated fintech - payments, lending, neobanking, wealth, and insurtech - so we understand payment-flow security, PCI-DSS and SOC 2, cloud scale, and the technical diligence investors and banking partners run. You get a fintech security company that speaks to your engineers and your auditors alike, prioritizes the controls that actually unblock deals, and works at a pace a growing startup can absorb.

Do you support RBI- and SEBI-regulated fintech in India?

Yes. For Indian fintech we align to the RBI and SEBI expectations that apply to your licence and product - outsourcing and cloud guidelines, data localization, VAPT and cyber-resilience for NBFCs, and DPDP for customer data - alongside the global frameworks (PCI-DSS, SOC 2, ISO 27001) your enterprise and cross-border deals require.
