Paidy – a Japanese Financial Institution in the Cloud

Paidy is a Fintech leader in delivering cardless payments and other financial services to the Japanese mass market and businesses. Its solutions are at the forefront of revolutionizing online and mobile payments, P2P transfers, personal finance, and merchant settlement. Paidy enables customers to check out using only their email address and a mobile phone number. No credit card or preregistration is needed. To prevent fraud, every transaction is authenticated using a PIN over SMS. Customers can shop now and pay one consolidated bill the following month.

Paidy’s entire platform runs in the cloud—primarily across multiple AWS accounts, but also Azure and GCP. It has multiple test and development environments. With the platform processing financial transactions, security is of the highest concern. CISO Felix Beatty is responsible for optimizing Paidy’s overall security posture.

“We are essentially a financial institution in the cloud,” says Beatty. “Because we’ve grown so rapidly—having gained more than three million customers in under a year—there are areas of our business where we can improve; one of them is cloud security. Most of our services run in the cloud today, so we need cloud security solutions that immediately surface critical issues so we can resolve them quickly.”

Paidy’s Large-Scale Cloud Environment Makes Total Visibility a Challenge

Gaining visibility into everything on the Paidy platform is one of his top challenges. “We have a large and complex cloud environment; it’s difficult to manage all these dynamic assets,” Beatty says. “We have hundreds of developers trying to push microservices as fast as possible into the cloud, spinning instances up and down, creating backups, creating S3 buckets, and moving so fast that it’s very difficult to know at any given moment what we have. We need to know, ‘What is the current security posture of all of our cloud assets?’”

Jeremy Turner, Senior Cloud Security Engineer, is his right-hand man in securing the cloud environment. The two have been a team since before joining Paidy and know how to approach its security challenge.

Security Agents are Great—If and When They Work (Usually They Don’t)

“I’ve been doing this a long time,” says Turner. “I’ve learned that anything dealing with security and vulnerability usually requires installing some type of agent. If you’ve worked in infosec for a while, you know that agents break, they need to be updated, and they could be vectors for other security vulnerabilities.”

Turner admits that agents are great—if and when they work. “Usually they don’t. There are so many dependencies and other things to think about. An agent may or may not work on this Linux kernel, and the same is true for versions of Windows. There are just so many variables that come into play. After years of dealing with agents, then seeing how easy it is to install and use Orca, I knew that its agentless approach was both a major innovation and a game changer,” says Turner.

Legacy Vulnerability Scanners and AWS Tools Were Unfit

The Paidy security team had experience with a variety of legacy tools adapted for the cloud. Turner says, “I’ve used Trend Micro, Qualys, and Tenable, either in an enterprise environment or in testing. Tenable and Qualys both felt like they loosely bolted their legacy enterprise products onto the cloud. That doesn’t work well because you still have to deal with agents. We still have to contend with technology that isn’t meant for such things as serverless or containers.”

Paidy also ruled out using network scanners. According to Turner, “Having experience with non-authenticated scanners, I knew they had limited visibility and can create downtime.

“Authenticated scanners might provide you with more vulnerability data, but still require lots of work to configure, as well as elevated privileges. This opens your enterprise up to risk because you essentially have another shared account and password.”

Cloud providers such as Amazon do provide security scanning tools. “Amazon’s AWS Inspector, a vulnerability scanner, requires an agent. Usually it’s baked into the Amazon AMI, but it only works with certain AMIs,” he continues. “AWS GuardDuty ticks the box for a vulnerability scan and compliance check. But reporting is its biggest issue; using the data can be a challenge. It just pops out a list of vulnerabilities, then it’s up to us to figure out what to do about them.”

Beatty adds, “Because we have multiple AWS accounts and are multi-cloud, it was difficult to have a single view where we could monitor everything that is happening. Multi-cloud visibility was our number one issue. Secondarily, we don’t have the time and resources to orchestrate a tool using, for example, AWS services or something similar. We want to use a service that doesn’t require any agent—where we don’t need to regularly update it and it simply works.” For Paidy, Orca Security meets all of those needs and more.

Orca SideScanning™ Provides Much-Needed Visibility

The Orca Security platform is vastly different from other security tools. Delivered as SaaS, it reads cloud block storage out-of-band, from the side—hence the term SideScanning™. No code runs within a customer’s cloud environment. Instead, Orca builds a read-only model of their cloud environment, which it then scans to assess potential security issues.

Having full visibility is what Turner appreciates most. “Visibility is a problem every organization has. Orca almost immediately gave us both wide and deep visibility into our threat landscape,” says Turner. “When we take that data and show it to folks, their eyes open. We had an instance where Orca revealed an ‘imminent compromise’ of a system that’s been floating in a test environment for probably two or three years. The system was running a totally outdated OS. Once Orca identified it, we created a ticket for an engineer to immediately address. We were fortunate to capture the vulnerability before the system went into UAT and production.”

Beatty agrees on the value of visibility: “There’s no excuse for overlooking problems when they’re presented right there for you. When the Orca dashboard displays ‘imminent compromise,’ it doesn’t get any clearer than that.”

Orca also helps Paidy with account sprawl issues. “We run 12 AWS accounts,” says Turner. “We didn’t know what’s in them all, so we plugged them into Orca. Within 30 minutes we had insight as to what was running in all accounts. We couldn’t have done that so quickly any other way.”

Asset management is another function Orca Security provides to Paidy. Orca provides an inventory of  each asset’s location, metadata, and a vulnerability list. “It’s pretty cool when I can pick an instance and see who’s logged into it, how many failed login attempts there are, or what packages are installed on it. I appreciate being  able to do that without depending on an agent for every instance,” says Turner.

Orca Security Identifies and Protects PII, Easing Paidy’s Compliance Efforts

As Paidy gains more experience with the Orca Security platform, its team finds more ways to use the data it generates. “As a Fintech company, we’re very mindful of toxic combinations of data—Orca helps us with this,” says Turner. “For example, customers must provide their cellphone number to use our service. But if we’re dealing with home or email addresses combined with possible bank account information and purchase history, then we get into PII issues and Japanese data privacy regulations.”

Turner explains how Orca helps protect PII. “One feature lets us know if Orca suspects PII. It’s like a beacon telling us, ‘This server contains email addresses that don’t belong to paidy.com. What’s going on?’ We can then investigate. Right now the tool doesn’t say, ‘Here’s a toxic combination of data’ but it does show us where to hunt. We had a situation where the data science team created a database joiner that led to such a toxic combination of data. Orca helped us catch it in time to nip it in the bud.”

Paidy must comply with a number of data privacy laws. Japan’s Cross-Border Privacy Regulation is similar to the EU’s GDPR, and the country’s Personal Information Protection Law was enacted in 2004. Orca helps prove to auditors that Paidy is fully capable of identifying and encrypting personal information. Paidy rests easy knowing it has the capability to scan for vulnerable PII.

Turner uses Orca Security’s integration with Jira to open tickets. In turn these trigger workflows so people and processes can take appropriate actions; for example, to encrypt sensitive data or to remediate other issues that Orca finds.

Orca Increases Paidy Revenue by Accelerating Merchant Onboarding

Orca helps Paidy onboard more merchants, thereby increasing its revenue. “Typically merchants want to do a third-party security review of us,” says Beatty. “Orca makes it easier for us to show that we’re scanning for vulnerabilities and mitigating as appropriate. This puts merchants at ease about our security posture and helps establish trust with them.

Beatty considers what it would cost if his team had to integrate and customize multiple legacy solutions to get visibility into their environment. Paidy estimated it would require two FTEs and half a million dollars per year to spin up and manage such a solution—a cost considerably higher than the Orca service that is fully managed and maintained on its behalf.

“When I talk to colleagues about Orca, I tell them it gives us insight across all our cloud environments—not only AWS, but also Azure and GCP. The more accounts we have, the more value we get because now we know what our people are running,” says Beatty.
