The organization was already using Akamai WAF across parts of its banking ecosystem. However, its stock brokerage and trading platforms had fundamentally different requirements.
These platforms supported live trading, including an EXE-based broker application, customer-facing web and mobile apps, and backend systems communicating over custom ports and socket-based connections. Latency sensitivity, fixed market hours, and zero tolerance for disruption meant traditional web-only security controls were insufficient.
The organization’s trading ecosystem included:
This hybrid architecture significantly increased both onboarding complexity and operational risk.
Sanity Checks Without a Safety Net
The presence of custom ports, socket connections, and tightly coupled backend systems made traffic validation extremely difficult. Any misconfiguration could directly impact order execution, customer experience, or regulatory compliance.
There was no room for trial or error
Zero Downtime Was Non-Negotiable
Trading platforms operate on strict market schedules. Even brief interruptions could lead to financial loss, reputational damage, and regulatory scrutiny.
The organization required WAF onboarding with zero downtime, ensuring uninterrupted trading during deployment, testing, and go-live.
A Hard Limitation with the Existing WAF
The existing WAF could not support custom ports and socket-based communication, making it unsuitable for securing the stock brokerage and trading environment. This limitation triggered the search for an alternative.
More Than Security: Adhering To SEBI Compliance Regulations
At the same time, the organization had to meet multiple SEBI cybersecurity mandates, including:
Meeting these timelines consistently across a complex digital ecosystem was essential to maintaining regulatory standing
The organization partnered with Indusface AppTrana WAAP, an AI-powered, fully managed application protection platform, to secure its trading and investment platforms.
The engagement focused on one core principle: secure live trading systems without disrupting them.
Zero-Downtime Onboarding of the Core Trading Platform
Indusface onboarded the customer’s core trading application with zero downtime, led by its dedicated SOC team.
The application was first deployed in monitoring mode to observe real production traffic and establish accurate baselines. Protection was moved to blocking mode only after thorough validation, ensuring zero false positives. The entire activity was done by Indusface services team in consultation with the customer.
This process involved close coordination between Indusface and the customer’s teams to validate traffic flows across web, API, and hybrid components, including custom ports and socket-based communication, all while trading remained uninterrupted.
Phased Expansion Across Applications
After successfully securing the core trading platform, coverage was expanded through a phased rollout.
Applications were onboarded incrementally, following a structured approach that included planned change of windows, comprehensive testing, and joint validation before moving to production. Indusface now protects around 60 applications.
Full-Spectrum Protection Across Application Types
AppTrana delivered unified protection across:
This ensured consistent security for customer-facing, broker-facing, and backend systems.
SEBI-Aligned Vulnerability Management and Virtual Patching
To meet regulatory requirements, AppTrana enabled:
This reduced exposure even when permanent fixes could not be deployed immediately.
Further with SwyftComply, they received clean, zero-vulnerability reports within 72 hours that helped them stay compliant with application security audit requirements.
AI-Powered, Fully Managed Security with Zero False Positives
Given the sensitivity of trading workflows, AppTrana maintained zero tolerance for false positives. AI-driven detection, combined with 24×7 SOC oversight, ensured:
What started with a few critical applications expanded steadily over time. Today, approximately 60 financial services applications are protected using AppTrana. In the last one year, AppTrana WAAP has delivered:
This case study isn’t about replacing a WAF. It’s about proving that high-frequency, SEBI-regulated trading platforms can be secured without downtime, without false positives, and without compromising compliance. And that is what makes the result worth paying attention to.
All while securing the live trading platform, onboarding custom ports and socket-based traffic, and meeting stringent SEBI cybersecurity requirements without interrupting a single trading session.
This is the story of how a leading Indian stock brokerage firm re-architected its application security without slowing markets, disrupting brokers, or compromising compliance.
The customer is a leading Indian stockbroking and financial services organization operating at scale across equity trading, derivatives, and investment products. The firm supports a growing customer base of over 7.5 lakh investors, with over 80,000 daily active users, and processes high volumes of time-sensitive trading transactions every day.
