Kirill Firsov Explains Why Offensive Security Is Crucial in the Financial Sector


In today’s digital world, financial institutions like banks, fintech companies, and cryptocurrency platforms face constant cyber threats. Hackers are always finding new ways to break into systems, steal data, or disrupt services. According to Kirill Firsov, chairman and co-founder of the cybersecurity firm FearsOff, the best way to deal with these threats is to stop being reactive and start being proactive. This is where offensive security comes in.
What Is Offensive Security?
Test your systems as a real hacker would in order to implement offensive security. Instead of waiting for an attack to happen, cybersecurity experts simulate attacks to find weaknesses before criminals do. It’s a hands-on, proactive method that helps organizations fix problems before they cause damage.
Some common offensive security practices include:
Penetration testing involves simulating hacks to identify vulnerabilities in applications or systems.
Red teaming: A comprehensive simulated cyberattack to evaluate the defences of the business.
Vulnerability assessment: Scanning systems to spot issues that could be exploited.
Why the Financial Sector Needs It
Hackers frequently target the financial industry. It handles:
Large sums of money
Sensitive customer data
Critical daily transactions
Because of this, attackers see it as a goldmine. A single data breach can harm a company's reputation and cost millions of dollars. Kirill Firsov says, “Financial systems are complex and high-value. As a result, they are appealing to attackers and challenging to defend.
How Offensive Security Helps
Firsov explains that offensive security brings several important benefits to financial institutions:
1. Find Problems Early
Regular system testing allows businesses to address vulnerabilities before hackers find them.
2. See the Bigger Picture
Simulated attacks give a real sense of how effective current defenses are not just on paper, but in practice.
3. Prepare for Real Incidents
Offensive security helps teams train for actual attacks, so they can respond faster and better when it counts.
4. Stay Compliant
Many regulations require regular security tests. By using offensive security, you may keep up with those regulations and stay out of trouble.
5. Earn Trust
Customers feel safer when they know a company is serious about cybersecurity and actively testing its systems.
A Change in Mindset
One key takeaway from Kirill Firsov’s approach is this: organizations need to shift from reactive to proactive thinking. Find your weaknesses on your own instead of waiting for a cyberattack to expose them.
“Too often, companies only act after something bad happens,” says Firsov. “Offensive security turns that around. You go looking for threats before they become real problems.”
