Website Security for Financial Advisers UK: FCA Compliance and Cyber Risk

Why Financial Advisers Are Prime Targets

Independent financial advisers (IFAs) and wealth management firms handle some of the most sensitive data imaginable — investment portfolios, pension values, inheritance details, tax returns, and banking information. For cybercriminals, a successful attack on a financial adviser's systems isn't just a data breach — it's a direct route to financial fraud.

The Financial Conduct Authority (FCA) has made cybersecurity a regulatory priority. Firms that suffer preventable breaches face enforcement action, not just reputational damage.

FCA Cybersecurity Expectations

The FCA doesn't publish a single "cybersecurity checklist" but its expectations are clear across several frameworks:

**Operational Resilience (PS21/3)** — Since March 2022, FCA-regulated firms must identify important business services, set impact tolerances for disruption, and test their ability to stay within those tolerances. A cyberattack that takes your client portal offline for days breaches operational resilience requirements.

**SYSC 8 — Outsourcing and Third-Party Risk** — Your website platform, CRM, and any cloud services you use are third-party dependencies. You remain responsible for their security.

**The Consumer Duty** — Requires firms to deliver good outcomes for retail customers. A data breach that exposes client financial data directly undermines this duty.

**Breach Reporting** — Material cyber incidents must be reported to the FCA. Attempting to conceal a breach carries serious consequences.

The Specific Risks for Adviser Websites

Client Portal Vulnerabilities

Many IFAs use third-party client portals (Intelliflo, Voyant, Transact). These platforms have their own security teams — but your integration with them, the credentials your staff use to access them, and the links you embed on your website create additional attack surface.

Phishing via Domain Spoofing

If your email domain lacks proper SPF, DKIM, and DMARC records, criminals can send emails to your clients that appear to come from your firm — directing them to fake investment platforms or requesting bank transfers. This is a direct fraud vector. See our guide on [subdomain enumeration and email security](/blog/what-is-subdomain-enumeration).

Credential Stuffing on Staff Accounts

Financial advisers often reuse passwords across personal and professional accounts. Attackers use leaked credential databases to attempt automated logins against your CRM and email. Without MFA, one leaked password is enough. Learn more about [credential stuffing attacks](/blog/what-is-credential-stuffing-attack).

Insecure Contact and Fact-Find Forms

Online fact-find forms collect pension values, income figures, and investment goals. These forms often lack proper input validation and may transmit data insecurely. A compromised form is a direct source of client financial data.

Supply Chain Attacks

Your website may rely on dozens of JavaScript libraries, plugins, or third-party widgets. A [supply chain attack](/blog/what-is-supply-chain-attack-website) that compromises one of these can inject malicious code into every page your clients visit.

How to Secure Your Financial Adviser Website

1. Enforce HTTPS and HSTS

Every page must be served over HTTPS. Implement HTTP Strict Transport Security (HSTS) to prevent protocol downgrade attacks. Your SSL certificate must be valid and auto-renewing.

2. Secure All Staff Accounts

- Multi-factor authentication on email, CRM, and all client platforms — non-negotiable - Password manager for all staff — unique passwords for every service - Regular access reviews — remove credentials for staff who have left

3. Fix Your Email Domain Records

Add SPF, DKIM, and DMARC records to your domain immediately. A DMARC policy of `p=reject` prevents spoofed emails from reaching your clients' inboxes.

4. Conduct Regular Penetration Testing

The FCA expects regulated firms to test their cyber defences. An annual [penetration test](/blog/penetration-testing-saas-startups-uk) of your website and client-facing systems demonstrates due diligence. Automated tools like [Yrzo AI](https://yrzoai.dev) can complement annual pen tests with continuous scanning.

5. Implement a Cyber Incident Response Plan

Before a breach happens, document: - Who is responsible for incident response - How you will notify the FCA (within timescales they specify) - How you will notify affected clients - Which IT contacts or forensics firms you will engage

6. Vet Third-Party Suppliers

Ask your website developer, CRM provider, and portal provider for their security certifications (Cyber Essentials, ISO 27001). Under FCA SYSC 8, you must monitor third-party risk.

Cyber Essentials and ISO 27001

**Cyber Essentials** certification demonstrates basic cyber hygiene — five technical controls that protect against the majority of common attacks. The UK government requires it for some government contracts; the FCA views it positively.

**ISO 27001** is the international standard for information security management. It's more comprehensive and signals serious commitment to cybersecurity — increasingly expected by institutional clients and due diligence processes.

Key Takeaways

Financial advisers hold high-value client data and operate under FCA regulatory scrutiny. A preventable cyberattack doesn't just cause client harm — it triggers regulatory enforcement. Secure your email domain, enforce MFA on all accounts, test your website regularly, and have an incident response plan ready.
