A financial trading firm needs layered security: managed endpoint protection, application allowlisting, multi-factor authentication, managed email security, staff awareness training and tested backups, plus tight controls on payments. Trading firms move money and are heavily targeted, so no single control is enough. Depth is what keeps client funds and data safe.
The biggest threats are payment fraud, account compromise and attacks that try to disrupt trading. Here’s the security that defends against them.
1. Endpoint protection and allowlisting
Managed endpoint protection on every machine, combined with application allowlisting so only approved software can run, blocks malware and ransomware before they can take hold. For a firm holding client money, that is essential.
2. Email security and payment verification
Most fraud starts with email. Managed filtering, impersonation protection and a firm rule to verify any change of payment details by phone protect your money at the point it matters most.
3. Strong authentication and access control
MFA on every account, and access granted only where needed, mean a stolen password alone cannot get anyone in or reach sensitive systems. This is the backbone of keeping attackers out.
4. Trained people and tested backups
Regular security awareness training keeps your team alert to the scams aimed at them, and tested, isolated backups mean an attack never costs you your data. Technology and trained people together are far stronger than either alone.
A real example: an attack stopped early
We supported a technology firm serving trading desks where managed endpoint protection and monitoring flagged at-risk machines and a suspicious mailbox rule, letting us act before any harm was done. Catching these signals early is exactly what layered security is for.
What this should cost
For a financial trading firm, this security sits within managed IT at about £45 to £100 per user per month, rather than being a separate line item. Buying it as part of a managed service means the controls are maintained, monitored and tested, not just installed once and forgotten.
The threats that hit trading firms hardest
The attacks we see most often target money and access:
- Business email compromise and payment redirection
- Account takeover through phishing and stolen credentials
- Malware and exploits aimed at unpatched or unrestricted machines
- Theft of client and position data
- Downtime that stops trading at the worst moment
Where to start
If you are unsure of your exposure, begin with the basics that stop most attacks: multi-factor authentication everywhere, application allowlisting, managed email security, and tested backups. Confirm them with Cyber Essentials, then build from there.
What a managed service includes
For a trading firm, this security is delivered as part of a complete managed service that covers:
- Helpdesk and support for your team, Microsoft 365 and core business apps
- Device management for laptops and servers: monitoring, patching and updates
- Secure access, including remote and privileged access where it is needed
- Managed cyber security: endpoint protection, allowlisting, email security and MFA
- Backup and tested recovery of your data and Microsoft 365
- Vendor coordination with your software, cloud and connectivity suppliers
- Clear reporting and a forward IT plan, not just reactive fixes
The result is fewer incidents, faster recovery, and evidence you can show clients and regulators.
Where to start if you are not sure
If you are unsure of your exposure, begin with the controls that stop most attacks: multi-factor authentication on every account, application allowlisting so only approved software runs, managed email security, and backups you have actually test-restored. These four close the majority of the gaps attackers exploit.
From there, confirm the basics with Cyber Essentials, add monitoring that leads to action rather than just alerts, and review privileged access so no one has more than they need. A short review will tell you where you stand and what to fix first.
Why the cheapest quote costs more
It is tempting to pick the lowest number, but on a trading desk minutes of downtime, a missed or unrecorded communication, or a redirected payment costs far more than the gap between a cheap contract and a good one. The right question is not the lowest price, but who keeps you trading, compliant and protected.
