⭐⭐⭐⭐⭐ Most penetration testers deliver automated scanner reports full of false positives. I deliver real, exploitable vulnerabilities with working Proof of Concepts (PoCs), business-focused risk analysis, and developer-friendly remediation guidance-the exact weaknesses an attacker would exploit in production. I'm a Cybersecurity Engineer, Penetration Tester, Cloud Security Engineer, and Ethical Hacker with 12+ years of hands-on experience helping organizations strengthen their security posture. I've completed projects for 663+ clients across 36 countries, delivered 900+ security assessments, identified 2,700+ vulnerabilities, and maintained an 80% repeat client rate by focusing on practical results instead of generic reports. Whether you need a Cybersecurity Engineer to strengthen your infrastructure, a Penetration Tester for compliance, a Cloud Security Engineer to secure AWS, Azure, or GCP, or an experienced Ethical Hacker to simulate real-world attacks, I deliver actionable results that reduce business risk. Why Clients Choose Me ✔ 12+ years of professional Cyber Security experience ✔ 663+ clients across 36 countries ✔ 900+ penetration testing engagements ✔ 2,700+ vulnerabilities identified ✔ 500+ Critical & High-risk findings ✔ 140+ Cloud Security assessments ✔ 75+ Incident Response investigations ✔ 80% repeat client rate As a Cybersecurity Expert, I've helped startups, enterprise organizations, healthcare providers, fintech companies, SaaS businesses, blockchain platforms, and eCommerce companies improve Cyber Security, strengthen Cloud Security, and prepare for SOC 2, HIPAA, ISO 27001, and PCI DSS. Core Services Web Application Penetration Testing As a Penetration Tester, I identify vulnerabilities automated scanners miss, including SQL Injection, XSS, SSRF, XXE, CSRF, RCE, IDOR, authentication and authorization flaws, business logic vulnerabilities, API weaknesses, and OWASP Top 10 risks. Every Penetration Tester engagement simulates realistic attacker behavior rather than simply generating automated scan results. Cloud Security As a Cloud Security Engineer, I secure AWS, Azure, and Google Cloud Platform environments through comprehensive Cloud Security assessments covering IAM, Kubernetes, Docker, cloud storage, VPC architecture, serverless security, DevSecOps, CI/CD pipelines, Infrastructure as Code, secrets management, logging, and monitoring. My Cloud Security reviews regularly uncover privilege escalation paths, exposed storage buckets, insecure IAM configurations, vulnerable Kubernetes deployments, and cloud misconfigurations before attackers exploit them. Infrastructure & Mobile Security Infrastructure penetration testing includes Windows, Linux, Active Directory, VPNs, wireless networks, privilege escalation, and lateral movement. Mobile security assessments cover Android, iOS, reverse engineering, static and dynamic analysis, API security, secure storage, certificate pinning, root detection, and jailbreak detection. As a Cybersecurity Engineer, I evaluate infrastructure from an attacker's perspective while providing practical remediation recommendations. Secure Code Review & Incident Response Manual code reviews, SAST, DAST, malware analysis, digital forensics, threat hunting, cloud forensics, and Incident Response. I frequently collaborate with Java Developer teams, DevOps engineers, architects, security teams, and every IT Project Manager responsible for secure delivery and reliable IT Service operations.

I’m Muhammad Ahmad Bilal, a CISSP-certified Security Architect and Information Security Manager who works at the intersection of security engineering, threat detection, and AI. For the past 9+ years I’ve been designing and running security programs at government scale, protecting critical national applications, large user bases, and high-value data across the public sector. I specialise in turning noisy, complex environments into predictable, defensible systems. That’s included building ML-driven APT detection using TensorFlow and PyTorch, modernising SIEM/SOAR stacks to cut detection and response times by around 40%, and embedding security into the SDLC so vulnerabilities are caught before they ever reach production. I’ve led Zero Trust initiatives, redesigned IAM around least privilege, and driven end-to-end implementations of governance, risk, and compliance programmes aligned with standards like ISO 27001, NIST, PCI, GDPR, and HIPAA. I’m also an educator by choice. As a Lecturer at NUST, I’ve taught Computer and Network Security, Cryptography, Operating Systems, and Data Structures, and supervised 20+ research projects in cybersecurity and machine learning. My academic work includes publications on: - Deep learning–based intrusion detection for IoT - Protocol-aware IDS using datasets such as UNSW-NB15 and Bot-IoT - Federated learning with explainable AI for malicious traffic detection and cellular traffic prediction What I do best: - Design security architectures for large, heterogeneous environments that can actually be operated and maintained by real teams. - Build and tune detection & response: SIEM, EDR, and SOAR use cases, threat hunting workflows, and playbooks that reduce noise while catching what matters. - Integrate security into delivery through secure SDLC practices, code review guidelines, and automation that supports developers instead of blocking them. - Make compliance meaningful, mapping real technical and process controls to standards and regulations so they translate into measurable risk reduction. - Develop people and teams, mentoring analysts and engineers so security becomes an organisational capability, not a one-team bottleneck. In simple terms, my work is about building security systems—technical, procedural, and human—that don’t fall apart the moment something real happens.

I help small and mid-sized businesses secure and streamline their Microsoft , cloud, identity, and end-user environments. With 12+ years of experience across IT operations and cybersecurity, I support organizations that need a trusted expert to improve security posture, stabilize systems, and reduce day-to-day technology risk without adding unnecessary complexity. I can help with: • Microsoft security reviews and hardening • Entra ID / Azure AD, MFA, Conditional Access, and identity governance • Intune and endpoint management • Email security, SPF, DKIM, DMARC, and Defender policy configuration • SharePoint, Teams, and Microsoft tenant administration • Network and infrastructure security improvements • Incident response planning and security baseline assessments • Ongoing IT support for cloud and hybrid environments Clients work with me when they need someone who can communicate clearly, solve problems quickly, and bridge the gap between IT operations and cybersecurity. If you need help strengthening your Microsoft environment, improving identity and endpoint security, or building a more reliable IT foundation, I’d be happy to discuss your project.

Chirag has spent almost 15 years in cybersecurity and worked in 10 different countries with talented cyber engineers. So, he knows the difference between a virus and a worm. Early in his career, he provided network security for Fortune 500 clients before advancing to cybersecurity, where he then spent his time learning and securing multiple clouds. His journey led him to Australia, where he worked with the government before starting his company and consulting for South Australia Health Department and a major bank. He won several prestigious awards and earned around 26 technical certifications. Currently, he is working with a team of people much smarter than him at Cybernara. You can find him geeking out on LinkedIn at Chirag’s LinkedIn. Also, don’t forget to say hi.
