Security Engineering

Explore the epitome of security engineering — where expertise meets innovation and your digital assets are shielded by a legacy of excellence.

Our comprehensive approach encompasses every facet of your digital ecosystem. From rigorous code analysis to meticulous penetration testing, we identify vulnerabilities before they can be exploited and integrate security seamlessly into your software development lifecycle.

What We Deliver

Five integrated service areas — including dedicated coverage for AI-powered applications — spanning the full security lifecycle.

AI Application Security

As AI becomes core to product architecture, it introduces a distinct class of vulnerabilities that traditional security testing does not cover. We assess AI-powered applications across four architectural tiers — delivering targeted findings and remediation guidance aligned to the OWASP LLM Top 10.

Vanilla AI

Direct LLM API integration

  • Prompt injection & adversarial input testing
  • Jailbreak resistance assessment
  • Sensitive data leakage via model responses
  • Insecure API key & credential management
  • Excessive model permissions & unauthorized actions
  • OWASP LLM Top 10 assessment
Static RAG

LLM + fixed knowledge base / vector store

  • All Vanilla AI checks
  • Knowledge base & document poisoning
  • Vector store access control & tenant isolation
  • Indirect prompt injection via ingested documents
  • PII & confidential data exposure in retrieval outputs
Dynamic RAG

Real-time retrieval, live data sources & agents

  • All Static RAG checks
  • Real-time data source manipulation & poisoning
  • Agentic tool/function call security & privilege escalation
  • Malicious content injection via web crawl or live feeds
  • Context window manipulation & token smuggling
Agentic AI

Autonomous agents with tool use, planning & multi-agent orchestration

  • Prompt injection via tool outputs & external data feeds
  • Privilege escalation through chained tool calls
  • Unauthorized autonomous action & goal hijacking
  • Memory poisoning (short-term & long-term memory corruption)
  • Multi-agent trust boundary violations & agent impersonation
  • Insecure tool/plugin integrations & unvalidated I/O
  • Unbounded resource consumption & denial-of-service via agent loops
  • Audit trail integrity & agent action traceability

Vulnerability Assessment & Penetration Testing (VAPT)

Our certified security experts systematically identify and exploit vulnerabilities across your entire attack surface. We cover OWASP Top 10 assessments on Cloud based Web applications, Android mobile apps, REST API and GraphQL endpoint pentesting, network and infrastructure pentesting, and IoT pentesting — delivering detailed, prioritised remediation reports.

Governance & Compliance Engineering

We guide you through the full compliance journey — from gap analysis and controls implementation to certification readiness and ongoing audit support. Our coverage spans ISO 27001 ISMS implementation and certification, ISO/IEC 42001 AI Management System, SOC 2 Type I readiness and Type II certification, HIPAA PHI/PII data protection controls, GDPR and India's DPDP Act data privacy and consent management. We also provide Virtual DPO services for continuous privacy governance.

Security Engineering

We embed security into every layer of your software and infrastructure. Our engineers run structured threat modelling using OWASP Threat Dragon and Microsoft Threat Modeling Tool, perform static analysis with SonarQube, Semgrep, and Checkmarx, and execute dynamic analysis with OWASP ZAP and Burp Suite. Cloud security posture is assessed across AWS, Azure, and GCP — surfacing vulnerabilities and architectural weaknesses before they become costly incidents.

Cyber Security Awareness & Training

Our internal security experts curate thorough online training programmes equipping your staff with the knowledge to defend against potential cyber threats and reduce the likelihood of inadvertent data breaches. A well-informed workforce is less susceptible to social engineering attacks, and adherence to best practices by every team member enhances overall organisational security.

The Hybrid Approach

Automated scanners are good, but they miss logical flaws. Our certified security engineers manually verify every finding and probe deep into your application logic to uncover complex attack vectors that tools simply cannot find — delivering zero false positives and truly actionable reports.

Frequently Asked Questions

Common questions about AI application security, VAPT, and compliance.

AI Application Security testing evaluates LLM-powered products across four tiers — Vanilla AI (direct API calls), Static RAG (fixed knowledge base), Dynamic RAG (real-time retrieval and live data sources), and Agentic AI (multi-step autonomous workflows). Coverage spans the OWASP LLM Top 10 — including prompt injection, sensitive data leakage, unauthorized actions, and supply chain attacks — alongside infrastructure assessment and application-layer vulnerability testing.

QuarkSek's Governance & Compliance Engineering covers ISO 27001 (information security), ISO/IEC 42001 (AI management systems), SOC 2 Type I & II, HIPAA, GDPR, and India's Digital Personal Data Protection (DPDP) Act.

Every engagement combines automated scanning with manual verification. We begin with threat modelling using OWASP Threat Dragon and the Microsoft Threat Modeling Tool, run static analysis (SAST) with SonarQube, Semgrep, and Checkmarx, then move to dynamic and manual testing with OWASP ZAP and Burp Suite across the categories in our toolkit — network, web, mobile, vulnerability scanning, OSINT, and AI/LLM security. Our engineers manually verify every finding, so reports contain no false positives.

Yes. QuarkSek's Security Engineering services are designed to be affordable and practical for startups and mid-sized businesses, with flexible engagement models and no long-term lock-in contracts. Web application penetration testing starts at $599 per target, and compliance readiness assessments start at $1,499. A free penetration test is available for early-stage startups.
