Stop Breaches.
Before They Start.
We give engineering teams in India clear visibility into exploitable vulnerabilities across web apps, APIs, and AI-powered products - before attackers find them.
HOW WE WORK
THE CHALLENGE
Fast-Moving Teams Create Real Attack Surface
Every new API, every deployment, every AI feature is a potential entry point. Most teams only find out after a breach.
No Visibility Into Risk
Most vulnerabilities sit undetected for months. Without continuous testing, your attack surface grows with every deployment your team ships.
AI Features Ship Untested
Chatbots, copilots, and AI agents go live without anyone checking for prompt injection, data leakage, or excessive agency - risks a normal web scanner will never catch.
Speed Creates Blind Spots
Every sprint ships new risk. Without security in your pipeline, you accumulate technical debt that attackers will eventually collect on.
THE SOLUTION
Security Visibility and Expert Testing. One Team.
From initial assessment to remediation verification, we handle every step of your security posture improvement.
Real Exploits, Not Scanner Noise
We manually verify every finding. No false positives, no padded reports.
AI Security Specialists
Deep expertise in LLM applications, prompt injection vectors, and agentic/tool-use security.
Plain-English Reporting
Every finding explained in business impact, not technical jargon your board cannot act on.
Fix Verification Included
We re-test after your team fixes each vulnerability at no additional cost.

WHAT WE DO
End-to-End Security Coverage
From your web app and APIs to your AI agents, we test everything attackers target first.
Web/API Pentest
Manual and automated testing of your web applications and APIs to uncover injection flaws, broken authentication, and business logic vulnerabilities.
AI/LLM Security Assessment
Structured security testing of your AI and LLM-powered products against the OWASP Top 10 for LLM Applications - data leakage, insecure output handling, and agent risk.
Prompt Injection Testing
Adversarial testing of your prompts, agents, and guardrails for direct and indirect injection, jailbreaks, and system prompt leakage.
AI Threat Hunting
Ongoing monitoring for anomalous AI behavior in production - model abuse, data exfiltration attempts, and adversarial inputs, with incident response support.
WHY DEFENSIFY
Not Scanner Reports. Real Exploits.
I started Defensify because I kept seeing organizations receive security reports that listed vulnerabilities but never explained their real business impact or gave actionable remediation guidance. My background is in hands-on offensive security — bug bounty programs, vulnerability disclosure programs, and independent research across web application, API, and AI systems. Defensify exists to deliver the kind of assessment I would want to receive: manual, specific, and built around outcomes rather than checkbox compliance.

Certified engineers. Manual verification. Business-focused reporting. Every engagement.
Web/API Pentest
A comprehensive vulnerability assessment and penetration test of your web application and APIs, combining automated scanning with manual exploitation to find what scanners miss.
We focus on business logic flaws, authentication weaknesses, and injection vulnerabilities - including BOLA and broken object-level authorization across REST and GraphQL APIs - that represent real financial and reputational risk to your organization.
What You Get
AI/LLM Security Assessment
A structured security assessment of your AI and LLM-powered products, mapped against the OWASP Top 10 for LLM Applications. We test the model integration layer, not just the surrounding web app.
Coverage includes sensitive data leakage, insecure output handling, training data and RAG pipeline exposure, supply chain risk in third-party models and plugins, and excessive agency in tool-using assistants.
What You Get
Prompt Injection Testing
Dedicated adversarial testing of your prompts, system instructions, and guardrails. We attempt both direct injection - typed straight into the chat - and indirect injection, where malicious instructions are hidden inside a document, webpage, email, or tool output your AI reads.
We probe for jailbreaks, system prompt leakage, guardrail bypass, and cross-plugin injection in multi-agent and tool-using setups - and document exactly which attempts succeeded and why.
What You Get
AI Threat Hunting
A pentest is a point-in-time check; AI Threat Hunting is ongoing. We monitor your production AI systems for anomalous behavior - repeated jailbreak attempts, unusual tool invocation patterns, and signs of data exfiltration through model outputs.
When we find active abuse, we help your team investigate and respond - closing the loop between detection and remediation instead of leaving you with an alert and no next step.

Common Questions
Home / About
We Are The Shield.
Defensify was founded on one conviction: Indian engineering teams deserve enterprise-grade security, delivered honestly.
"Most security reports explain what is broken. Very few explain what it means for the business, or give you a clear path to actually fixing it. That gap is why Defensify exists."
— Anvesh S., Founder
Defensify was built by security engineers who grew frustrated watching companies ship vulnerable code, or worse - getting breached through vulnerabilities a real test would have caught.
We focus on modern engineering teams building web, API, and AI-powered products because we believe specialization matters in security. Generic security companies treat your LLM-powered features like just another web app. We don't.
Mission
To make enterprise-grade security accessible to every ambitious Indian tech company - not just the ones that can afford a Big Four consulting retainer.
Vision
An India where no growing tech company loses customer trust because of a web, API, or AI security gap that could have been identified and fixed.
Values
Honesty about what we find. Clarity in how we report it. Commitment to seeing it fixed. We don't inflate findings or exaggerate risk.
