A0 Cyber Security pairs 24x7 managed defense with offensive security built for the environments most testers won't touch — automotive systems, OT/ICS, medical devices, and embedded hardware, alongside full-spectrum web, mobile, cloud and network VAPT.
Specialized in automotive, OT, medical devices, and hardware — trusted across India's most regulated industries too.
Average time a threat goes undetected in enterprise environments.
Of breaches involve a human element — phishing, credential theft, privilege abuse.
Average cost of a data breach for Indian organizations in 2024.
"The question isn't whether you'll be targeted. It's whether you'll know when it happens."
Continuous defense, paired with offensive security specialized in automotive, OT, medical devices, and hardware — the environments generalist testers can't reach.
Your infrastructure doesn't rest. Neither do we. A0's Managed Security practice delivers 24x7 monitoring, detection, and response across your endpoints, networks, cloud workloads, and identities — anchored by a tuned SIEM and led by experienced analysts. We become your security operations layer, without the overhead of building one in-house.
We specialize where most testers stop. A0's Offensive Security practice is built around automotive & EV systems, OT/ICS environments, medical devices, and embedded hardware — chip-off, firmware, and protocol-level attacks included — backed by full-spectrum web, mobile, API, cloud, network, and red team testing.
Every VAPT firm tests web apps and networks. A0 goes into the hardware — automotive systems, industrial control, medical devices, and embedded platforms are our core specialization, on top of full-spectrum web, mobile, API, cloud, and red team testing.
ECU, CAN bus, telematics, and EV charging infrastructure — assessed the way an attacker with physical access would approach them.
PLCs, SCADA, and industrial protocols assessed without disrupting production — safety and uptime built into every test plan.
Implantable, wearable, and hospital-networked devices reviewed against FDA premarket guidance and IEC 62443/81001-5-1.
Chip-off, JTAG/SWD, side-channel, and firmware reverse engineering for any embedded platform — not just the software stack around it.
Also covered: Network VAPT, Web / Mobile / API Pentest, Cloud Pentest, Red Team, Secure Code Review, and Configuration Review.
We map your asset landscape, threat exposure, and compliance obligations before recommending anything.
We design a security program aligned to your industry's specific risk model — not a generic template.
We implement with minimal disruption. Every tool, every integration, every rule — tuned to your environment.
Continuous coverage, regular reviews, and a security posture that matures as your business grows.
"Every engagement begins with listening. We don't sell products. We solve problems."

Enterprise-Grade Security, Scaled to Your Environment
Most SIEM deployments end in one of two ways: complete alert fatigue from thousands of uncorrelated events, or a system so locked down it misses real threats.
A0 approaches SIEM as a living program — not a one-time installation.
Every assessment, every deployment, every report follows frameworks your auditors and regulators recognize.
"Methodology-driven delivery means consistent, defensible, audit-ready outcomes — every time."
Our team holds OSCP, CISA, CISM, CRISC, CEH, and ISO 27001 Lead Auditor credentials. The person who assesses your environment is the same person who understands how to break into it.
We are built around detection, monitoring, and response — not just periodic testing. Our defensive posture ensures you're protected between assessments, not just during them.
Whether you're a 20-person startup or a regulated enterprise, we build programs that match your risk profile, your budget, and your growth stage — not a pre-packaged tier.
No sales pitch. No generic audit template. Tell us what's keeping you up at night — we'll tell you exactly how we'd approach it.
