Phishing remains one of the most common ways cyber criminals target UK businesses, and protecting your business against phishing attacks is essential for women running small companies. A phishing attack uses email, text, phone calls or social media messages to trick someone into handing over passwords, bank details, or access to company systems. For women founders, where one mistaken click can lock accounts, expose client data, or trigger a regulatory fine, knowing how to spot and stop phishing is a business priority.
This guide explains the main types of phishing, the tactics attackers use, how to identify a suspicious message, and the practical steps you can take to protect your business. It also points to free UK government resources that can help you strengthen your defences without hiring a large IT team.
Why phishing matters for UK small businesses
According to the UK government’s Cyber Security Breaches Survey 2024, half of UK businesses (50%) identified at least one cyber security breach or attack in the previous 12 months. Of those that reported a breach, 84% said phishing attacks were involved (DCMS, 2024). Women-led businesses are not immune. Many operate with lean teams where one person manages finance, client relationships and operations, which can make a single compromised email account especially damaging.
Most phishing attacks are financially motivated. Criminals may want to steal money directly, commit invoice fraud, sell customer data, or install ransomware. Even a small business can be a valuable target because it may hold supplier details, customer records, or access to larger partner organisations.
The consequences of a successful phishing attack can include:
- Data breaches and loss of customer trust
- Financial theft or fraudulent payments
- Operational disruption from ransomware or malware
- Reputational damage and loss of contracts
- Regulatory action under UK GDPR and the Data Protection Act 2018
The Information Commissioner’s Office (ICO) can issue fines for failures to protect personal data. Under UK GDPR and the Data Protection Act 2018, organisations can be fined up to £17.5 million or 4% of global annual turnover, whichever is higher, for serious data protection failures. Phishing awareness is part of meeting your security obligation.
Common types of phishing attacks
Phishing comes in several forms. Understanding the differences helps you tailor your defences and train your staff effectively.
| Type | What it involves |
|---|---|
| Spear phishing | Highly targeted emails aimed at specific individuals, often using information from social media or company websites. |
| Whaling | Attacks directed at senior leaders or founders who control payments, payroll, or sensitive contracts. |
| Clone phishing | A legitimate email is copied and resent with a malicious link or attachment replacing the original. |
| Business email compromise (BEC) | Criminals impersonate a supplier, director, or client to redirect invoices or request urgent payments. |
| Smishing and vishing | Phishing via text message (smishing) or phone call (vishing), often pretending to be a bank or government body. |
Tactics phishing attackers use
Criminals rely on urgency, authority, and familiarity to pressure people into acting quickly. Common tactics include:
| Tactic | How it works |
|---|---|
| Email spoofing | Forging the sender address so the message appears to come from a colleague, bank, or trusted brand. |
| Link manipulation | Using misspelt domains, subdomains, or URL shorteners to hide a fake website. |
| Fake attachments | Embedding malware in files with extensions such as .exe, .scr, .zip, .docm, or .js. |
| Website spoofing | Creating a near-identical copy of a real login page to harvest credentials. |
| Urgent requests | Claiming an account will be closed, a payment is overdue, or a senior leader needs immediate action. |
How to identify a phishing email
Train yourself and your team to pause and check before clicking links, opening attachments, or transferring money. Key warning signs include:
- A sender address that does not match the organisation it claims to represent
- Generic greetings such as “Dear Customer” rather than your name
- Spelling mistakes, awkward phrasing, or unusual formatting
- Requests for passwords, payment details, or confidential information
- Unexpected urgency, threats, or offers that seem too good to be true
- Links that reveal a different destination when you hover over them
- Attachments you were not expecting, especially from unknown senders
If something feels wrong, verify it through a separate channel. Call the sender using a known number, log into the account directly via your browser rather than following a link, and report the message to your IT contact or security provider.
Protecting your business against phishing attacks
Effective protection combines people, processes, and technology. Relying on one layer alone leaves gaps. A multi-layered approach is the most reliable way to reduce risk.
Run regular awareness training
Your staff are your first line of defence. Training should cover password security, how to recognise phishing, what to do with suspicious messages, and how to report incidents. Use real examples from your sector where possible, and make training a regular event rather than a one-off session.
For women founders juggling multiple roles, short, practical training is often more effective than a single annual session. Include scenarios such as:
- Invoice fraud requests that appear to come from a known supplier
- Messages claiming to be from HMRC or Companies House
- Fake IT support requests asking for login details

Write and review cyber security policies
Your policies should set out who is responsible for cyber security, how to handle suspicious emails, how to manage passwords, and what to do if a breach is suspected. They should also cover the use of personal devices for work and the handling of sensitive data.
Review policies at least once a year, or sooner if your business changes systems, suppliers, or working patterns. Make sure all staff, contractors, and volunteers have read and understood them.
Use technical defences
Technical controls reduce the chance of phishing emails reaching inboxes and limit the damage if someone clicks a malicious link. Key measures include:
- DMARC, SPF, and DKIM: Email authentication standards that make it harder for criminals to send messages that appear to come from your domain.
- Multi-factor authentication (MFA): Adds a second step to logins, so a stolen password alone is not enough to access an account.
- Email filtering: Blocks or quarantines suspicious messages, links, and attachments before they reach users.
- Endpoint protection: Detects and responds to malware on laptops, phones, and other devices.
- Access controls: Limit user privileges so staff only have access to the systems and data they need.
- Regular updates: Keep operating systems, software, and apps patched against known vulnerabilities.
Consider Cyber Essentials certification
Cyber Essentials is a UK government-backed scheme that helps organisations protect themselves against common online threats, including phishing. Certification demonstrates to clients, insurers, and partners that you take cyber security seriously. Some public sector contracts require it.
The scheme covers five technical controls: firewalls, secure configuration, user access control, malware protection, and patch management (NCSC/IASME). You can self-assess or opt for Cyber Essentials Plus, which includes an independent audit.
Free UK resources to help you stay secure
Several UK organisations offer free guidance and tools for small businesses:
- National Cyber Security Centre (NCSC): The NCSC Small Business Guide provides practical advice on protecting your organisation. It also offers Exercise in a Box, a free toolkit to test your response to cyber incidents.
- Check your cyber security: A free NCSC service that helps UK organisations identify common email security weaknesses.
- Suspicious Email Reporting Service (SERS): Forward suspicious emails to [email protected]. Run by the NCSC, it investigates reports and removes malicious links where possible.
- Action Fraud: Report fraud and cyber crime to the UK’s national reporting centre. Call 0300 123 2040 or use the online reporting tool.
- ICO: Guidance on data protection obligations, breach reporting, and security expectations under UK GDPR.
You can also reduce financial exposure by reviewing whether cyber insurance is right for your women-led SME.
What to do if you suspect an attack
If you or a team member suspects a phishing attack, act quickly:
- Do not click links, open attachments, or reply to the message.
- Report it to your IT support, security provider, or designated person.
- Forward suspicious emails to [email protected].
- If credentials may have been entered, change passwords immediately and enable MFA.
- Check bank accounts, payment systems, and email rules for unauthorised changes.
- If personal data has been compromised, assess whether you need to report a breach to the ICO within 72 hours (UK GDPR).
Keeping calm and following a clear plan reduces the impact. Preparation is more valuable than panic.
Next steps to protect your business
Protecting your business against phishing attacks is not just an IT issue. It is a business priority that affects your finances, reputation, and legal obligations as a woman founder. By training your team, writing clear policies, using technical defences, and taking advantage of free UK resources such as the NCSC and Cyber Essentials, you can significantly reduce your risk. Start with one or two changes this week, build from there, and make cyber security part of how your business operates every day.
