How a FinTech Startup Accelerates Rapid Product Iteration Without Introducing Security Gaps With Xint

Z Enterprise, an innovative startup providing solutions ranging from tax refunds to tax management, is growing rapidly. Given the nature of startups, which require rapid management and updates of the product lifecycle, traditional security checks, which incur high costs and time every time, inevitably became a significant burden.

Working with Xint, Z Enterprise efficiently achieved compliance and established a thorough security system using Xint Web, precisely when needed and without any cost burden.

1. Challenges for Rapidly Growing Startups: ‘Rapid Product Lifecycles’ Versus ‘Security Compliance’

Since Z Enterprise handles customers’ tax and financial data, compliance with high-level security standards, including ISMS, was essential. However, in a startup environment where agility is required with limited resources, existing security diagnostic methods became an obstacle to innovation.

• Unpredictable domain expansion and cost burden: Manual diagnosis by experts incurred linear costs as the diagnosis domain and inspection targets increased. For startups that need to rapidly expand commercial services, security inspection costs can become a direct source of budget pressure.

• Agile product lifecycle response: As products are updated on a weekly or daily basis, one-time security checks performed once or twice a year have limitations in defending against security blind spots that occur during the frequent update process.

• Limitations of post-measure verification (implementation check): Even after vulnerabilities are discovered and patched, additional time and communication effort are continuously incurred during the 'implementation check' process to verify whether the measures have been completely addressed.

2. Xint Web: A Security Partner Tailored to Move at the Speed of Startups

Z Enterprise needed a flexible monthly plan that could scale up or down based on their release cadence, which was one of the reasons they went with Xint. 

3. Z Enterprise’s Synergy with Xint

① Simple implementation procedure, inspection of all assets within a short period

Because current security solutions depend on the scale of the targets to be inspected, there is inevitably a burden of high costs and inspection periods. However, as a SaaS, Xint Web offers a very simple service implementation process and provides an environment where assets can be continuously diagnosed as often as needed. Consequently, Z Enterprise was able to efficiently inspect a large number of websites within a short period without incurring significant costs.

② Proactive discovery of unexpected vulnerabilities and enhancement of internal security awareness

As a result of running Xint, Z Enterprise was able to identify potential security risks that were not detected during the previous inspection process. This not only enabled proactively blocking potential infiltration paths for actual attackers, but also served as a powerful motivator for the entire development and operations team internally, demonstrating "why product security and rapid vulnerability response are important."

③ Streamlining the complex implementation verification process

In the past, significant resources were consumed for re-verification following vulnerability remediation, but by utilizing Xint’s automated implementation check function, Z Enterprise was able to verify the results of the measures immediately. Thanks to this, securing evidence for compliance with standards such as ISMS has become much easier.

—--------------------------------------

Xint is the most practical security solution that breaks down the limitations of cost and time.

“For a rapidly expanding startup like ours, traditional, cumbersome, and expensive security diagnostic methods have always been a significant burden. Xint offers a solution at a reasonable cost within a short period.We were able to effectively identify potential security risk factors. Since they took care of everything from implementing measures to conducting compliance checks, responding to compliance became much easier. In particular, the fact that we could use it on a monthly basis when needed was the biggest advantage for a startup like ours that needs to use its budget efficiently.”
