Top 10: Cybersecurity Companies for Financial Services

Industrialised cybercriminal operations continue to target the banking, financial services and insurance (BFSI) sector at scale.

AI has only exacerbated the issue for BFSI organisations, with the technology increasing the speed and sophistication of fraud, phishing and network breaches.

In 2025, several high-profile incidents occurred, including the Lazarus Group attack on Bybit, which saw US$1.5bn in Ethereum stolen. Then there was the Global Bank Network Supply Chain Breach, which resulted in millions disappearing through unauthorised transactions and the MegaCorp data leak, where 20 million credit card records and personal details were exposed.

It is now a case of fighting fire with fire in the sector, with the BFSI sector now relying on AI to secure their networks and data.

In this week's Top 10, FinTech Magazine looks at the cybersecurity companies helping the BFSI sector protect infrastructure, data and financial networks.

10. Trend Micro

Founded: ​​​​​​​1998 
Headquarters: Tokyo, Japan / Texas, US 
CEO: Eva Chen

Trend Micro holds a unique position in banking by securing both modern cloud applications and critical legacy infrastructure.

Its Vision One platform has become a powerhouse, providing essential hybrid network compliance across AWS, Azure, and on-premises data centres.

Notably, its virtual patching shields vulnerable mainframes and older Windows servers from exploits without requiring reboots – a vital feature for core banking systems that cannot afford downtime.

9. Okta

Founded: 2009
Headquarters: California, US
CEO: Todd McKinnon

With open banking and fintech integration continuing across financial services, identity protection has become a primary focus for banks and insurers.

Okta is helping organisations secure open banking application programming interfaces (better known as APIs), ensuring third-party applications accessing customer information remain verified and authenticated.

The company now places emphasis on identity threat detection and response (ITDR).

Its Workforce Identity Cloud secures access to sensitive systems including financial portals, SWIFT terminals and trading platforms. By preventing credential theft, which remains one of the largest causes of data breaches in finance, Okta supports zero trust security models.

Its AI identity protection technology also blocks sophisticated deepfake biometric bypass attempts during customer onboarding.

8. Splunk (a Cisco company)

Founded: 2003
Headquarters: California, US
CEO: Chuck Robbins (Cisco CEO)

Following Cisco’s acquisition of Splunk, the platform now integrates with Cisco Talos Intelligence.

For financial security operations centres, also known as SOCs, this creates visibility between network infrastructure and security data.

Banks use Splunk’s Agentic AI capabilities to investigate low-level fraud alerts automatically, reducing the burden on security teams.

The platform also processes large volumes of log data to support compliance requirements including PCI-DSS, SOX and Basel III regulations.

This visibility across global banking systems makes Splunk an important platform for compliance officers and security analysts.

7. Check Point Software

Founded: 1993
Headquarters: California, US
CEO: Nadav Zafrir

Check Point Software focuses on AI-led threat prevention and network stability for financial institutions prioritising uptime and risk reduction.

Its Infinity architecture concentrates on blocking attacks before compromise occurs rather than responding after detection.

The company’s 2026 Quantum-Safe VPN modules are also undergoing trials at businesses seeking protection against future quantum decryption threats.

For central banks and clearing houses, where operational downtime can disrupt markets, Check Point’s reputation for stability and code quality continues to support adoption.

6. Proofpoint

Founded: 2002
Headquarters: California, US
CEO: Sumit Dhawan

Proofpoint delivers protection for organisations where phishing remains the entry point for most sophisticated attacks.

The company specialises in business email compromise, or BEC, where attackers impersonate executives to authorise fraudulent transactions and wire transfers.

Proofpoint also monitors insider threats and suspicious data exfiltration, helping wealth management firms protect sensitive client information.

In 2026, the company expands into AI data governance, helping firms monitor and redact personally identifiable information (often referred to as PII), within Microsoft Teams and Zoom communications in real time.

5. Fortinet

Founded: 2000
Headquarters: California, US
CEO: Ken Xie

Fortinet is a major security provider for retail banking branches and insurance offices.

Its FortiGate platform combines firewall technology with Secure SD-WAN, allowing financial organisations to secure ATMs and remote branches through a single appliance.

The company delivers encryption and threat protection at scale while maintaining lower deployment costs than many competitors.

Fortinet also continues to expand in operational technology security, protecting physical banking infrastructure including building management systems and vaults.

4. Zscaler

Founded: 2007
Headquarters: California, US
CEO: Jay Chaudhry

Zscaler provides a great deal of support for financial organisations moving away from legacy VPN infrastructure.

Its Zero Trust Exchange platform securely connects users to applications without placing them directly onto corporate networks, reducing exposure to cyber threats and helping firms comply with GDPR and data residency requirements.

The company also introduces AI Red Teaming capabilities through its SPLXAI acquisition, allowing banks to test internal gen AI systems for data leaks and vulnerabilities.

For remote banking staff and financial advisers, the platform provides cloud-first access controls designed to defend against internet-based threats.

3. Symantec (a Broadcom Company)

Founded: 1982
Headquarters: California, US
CEO: Hock Tan (CEO of Broadcom)

Symantec continues to operate as a leading data loss prevention provider for major global banks.

Financial institutions use the platform to classify and prevent sensitive information, including credit card details and personally identifiable information, from leaving corporate networks.

Its policy engine remains deeply integrated within compliance workflows and banking infrastructure, including SWIFT and clearing house protocols.

For highly regulated financial environments, Symantec continues to provide detailed controls for preventing data leaks.

2. CrowdStrike

Founded: 2011
Headquarters: Texas, US
CEO: George Kurtz

One of CrowdStrike's focuses is on ransomware and endpoint protection across banking environments.

Its Falcon platform operates across ATMs, laptops and financial systems, recording and monitoring endpoint activity to identify threats rapidly.

The Falcon Flex model also allows banks to switch between security modules including cloud security and next-generation antivirus services.

In 2026, Charlotte AI becomes a major tool for security analysts investigating nation-state activity targeting financial institutions and liquidity systems.

1. Palo Alto Networks

Founded: 2005
Headquarters: California, US
CEO: Nikesh Arora

Palo Alto Networks continues to lead among tier 1 financial institutions requiring advanced network and cloud security.

Its acquisition of CyberArk in late 2025 expands the company’s capabilities across privileged access and banking infrastructure security.

The Cortex XSIAM platform now serves as a benchmark for replacing traditional SIEM systems, enabling organisations to isolate infected systems in under 10 seconds.

Meanwhile, the Cortex and Strata platforms inspect encrypted high-frequency trading traffic while minimising latency.

By automating security operations through AI, Palo Alto Networks helps banks reduce manual SOC workloads and strengthen protection across hybrid data centre environments.
