Cybersecurity is paramount on this planet of digital funds. As senior vp and CISO at Visa, Subra Kumaraswamy leads cybersecurity efforts on the cost card providers big with a philosophy that he and his staff may at all times be doing extra.
“Day-after-day I get up and say, ‘What I ought to do higher?’” he tells InformationWeek. “Being pessimistic and being paranoid, P&P, which means always have a look at this as ‘glass half empty.’ What else we must be doing to make sure we’ve got a robust safety posture?”
Earlier than he stepped into the lead cyber job at Visa, Kumaraswamy constructed his profession by means of many various roles at many various corporations. He appears to be like again at these experiences and ahead to the ever-present must handle and strengthen cybersecurity in his present place.
A Various Set of Roles
Kumaraswamy considers himself an engineer and an issue solver at coronary heart. His first job was as a software program engineer on the College of Notre Dame; he was determining the best way to supply web providers throughout the campus earlier than the dot com growth started.
Since that first job, he has constructed expertise at corporations like Netscape, Solar Microsystems, eBay, and Intuit. He additionally hung out as an entrepreneur.
“In my journey, what outlined me was the range … of roles,” says Kumaraswamy. “I used to be capable of be a developer. I used to be capable of be an information middle architect. I used to be capable of run providers within the cloud, and I used to be capable of be an entrepreneur. And all of this helped me to create rather more of a holistic view.”
When he was at Netscape, the corporate was hit with a DDoS assault, the preliminary spark that obtained Kumaraswamy fascinated with cybersecurity. All through his profession, he has targeted on securing enterprises as they trip the waves of recent transformative know-how, whether or not that be the web, the cloud, or now, AI.

He was working as head of digital safety at Apigee, an organization that’s now a part of Google Cloud, specializing in API safety. Then got here a name from a recruiter.
“Visa was going by means of the entire transformation round creating open programs, opening up the platform to thousands and thousands of builders utilizing APIs,” Kumaraswamy remembers. “The hook was, ‘Hey, you are able to do this at scale.’ You possibly can deliver the identical mindset, your ardour, and all of the expertise … to one of many largest cost safety cost corporations on this planet.”
He accepted the position in safety engineering and safety structure in 2015. A decade later, he’s main cyber technique as the corporate’s CISO.
Cyber Management at Visa
Greater than 1,000 individuals work in cyber at Visa, in response to Kumaraswamy. “I’m actually pleased with the actual fact [that] the bench may be very robust. Now we have prime expertise throughout a number of areas, not simply within the US — throughout the globe,” he says.
That bench of expertise works in six vertical features inside cybersecurity: governance, danger and compliance; entry management and administration; cyber engineering; cyber protection; cloud safety; and safety structure and engineering.
Kumaraswamy works intently with Rajat Taneja, Visa’s president of know-how. “I’m very lucky to have a CTO who thinks cyber first,” says Kumaraswamy. “That units the tone on the prime. Saying that, ‘Hey, we do must innovate in know-how and funds. However should you don’t do cyber, nicely, nothing issues.’ It’s an existential risk for Visa.”
Avoiding Complacency
Gartner charges Visa’s cybersecurity maturity. “Once I began my profession path right here at Visa in 2015, it was about 3.2 out of 5,” Kumaraswamy shares. “For the final two years, we have been given a rating of 4.9 out of 5.”
Whereas these numbers are a testomony to Visa’s investments in cybersecurity, Kumaraswamy hardly sees them as a given. Cyber threats are fixed and ever-changing.
Trying again at his years with Visa, Kumaraswamy remembers working by means of the aftermath of the Log4J zero-day vulnerability in 2021. He and his staff spent 4 weeks sweeping a whole lot of functions utilizing Log4J and doubtlessly open to assault.
“It was across the clock effort and actually a whole lot of individuals, possibly hundreds of individuals, within the firm, have been concerned within the know-how to verify we mitigated this in a really brief order,” he says. “I feel that additionally gave us lots of publicity to how we must always take into consideration the subsequent Log4J.”
There will probably be, inevitably, extra zero days and extra cyberattacks. “While you get up within the morning, [the] very first thing you consider is, ‘Am I paranoid sufficient?’ Complacency is the enemy of safety,” says Kumaraswamy.
Pushing Cybersecurity Ahead
Kumaraswamy is at all times desirous about expertise and know-how in cybersecurity. Expertise is a perennial concern within the business, and Visa is trying to develop its personal.
The Visa Funds Studying Program, launched in 2023, goals to assist shut the talents hole in cyber by means of coaching and certification. “We’re providing this to all the staff. We’re providing it to our companions, just like the banks, our clients,” says Kumaraswamy.
Proper now, Visa leverages roughly 115 totally different applied sciences in cyber, and Kumaraswamy is consistently evaluating the place to go subsequent. “How do I [get to] the 116th, 117th, 181th?” he asks. ”That must be added as a result of each layer counts.”
In fact, GenAI is part of that equation. To date, Kumaraswamy and his staff are exploring greater than 80 totally different GenAI initiatives inside cyber.
“We’ve already taken about three to 4 of these initiatives … to the complete firm. That features the what we name a ‘shift left’ course of inside Visa. It’s now enabled with agentic AI. It’s decreasing the time to search out bugs within the code. It is usually serving to scale back the time to research incidents,” he shares.
Visa can also be taking its finest practices in cybersecurity and sharing them with their clients. “We are able to consider this as value-added providers to the mid-size banks, the credit score unions, who don’t have the dimensions of Visa,” says Kumaraswamy. “I’m actually excited to see how that may take form and make not simply Visa be the strongest hyperlink, however the complete cost ecosystem may be as robust as Visa,” he says.
