Cybersecurity is paramount on this planet of digital funds. As senior vice chairman and CISO at Visa, Subra Kumaraswamy leads cybersecurity efforts on the fee card companies big with a philosophy that he and his crew might 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, that means continuously have a look at this as ‘glass half empty.’ What else we needs to be doing to make sure we’ve a robust safety posture?”
Earlier than he stepped into the lead cyber job at Visa, Kumaraswamy constructed his profession by many alternative roles at many alternative corporations. He seems again at these experiences and ahead to the ever-present must handle and strengthen cybersecurity in his present place.
A Numerous 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 supply web companies 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 frolicked as an entrepreneur.
“In my journey, what outlined me was the variety … of roles,” says Kumaraswamy. “I used to be capable of be a developer. I used to be capable of be a knowledge heart architect. I used to be capable of run companies within the cloud, and I used to be capable of be an entrepreneur. And all of this helped me to create far more of a holistic view.”
When he was at Netscape, the corporate was hit with a DDoS assault, the preliminary spark that bought Kumaraswamy excited by cybersecurity.

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 the entire transformation round creating open programs, opening up the platform to hundreds of thousands of builders utilizing APIs,” Kumaraswamy remembers. “The hook was, ‘Hey, you are able to do this at scale.’ You possibly can convey the identical mindset, your ardour, and all of the expertise … to one of many largest fee safety fee 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 folks work in cyber at Visa, in keeping with Kumaraswamy. “I’m actually happy with the very fact [that] the bench may be very sturdy. 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 capabilities inside cybersecurity: governance, threat and compliance; entry management and administration; cyber engineering; cyber protection; cloud safety; and safety structure and engineering.
Kumaraswamy works carefully 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 need to innovate in know-how and funds. However for those who don’t do cyber, nicely, nothing issues.’ It’s an existential menace 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 the aftermath of the Log4J zero-day vulnerability in 2021. He and his crew spent 4 weeks sweeping a whole bunch of functions utilizing Log4J and probably open to assault.
“It was across the clock effort and actually a whole bunch of individuals, possibly 1000’s of individuals, within the firm, had been concerned within the know-how to verify we mitigated this in a really quick order,” he says. “I believe that additionally gave us a whole lot of publicity to how we must always take into consideration the following Log4J.”
There might 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 eager 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 abilities hole in cyber by coaching and certification. “We’re providing this to all the workers. 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 continually 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 crew are exploring greater than 80 totally different GenAI initiatives inside cyber.
“We’ve already taken about three to 4 of these initiatives … to your complete firm. That features the what we name a ‘shift left’ course of inside Visa. It’s now enabled with agentic AI. It’s lowering the time to seek out bugs within the code. Additionally it is serving to scale back the time to analyze incidents,” he shares.
Visa can be taking its greatest practices in cybersecurity and sharing them with their clients. “We will consider this as value-added companies 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 your complete fee ecosystem might be as sturdy as Visa,” he says.
