Capabilities

What We Do

Offensive and defensive security services built on real-world threat intelligence and operator experience.
🔓

Penetration Testing

Network, application, cloud, and physical security assessments. We simulate real adversaries — not checkbox scanners — to find what automated tools miss.

🔍

Threat Intelligence

Continuous monitoring of threat actor TTPs relevant to your industry. Actionable intel delivered to your SOC, not PDF reports that collect dust.

🚨

Incident Response

When a breach occurs, our team deploys within hours. Containment, forensics, recovery, and post-incident hardening — end to end.

🛡️

Red Team Operations

Full-scope adversary simulation including social engineering, physical access, and multi-stage attack chains. Test your people, not just your perimeter.

📋

Compliance & Audit

SOC 2, ISO 27001, NIST, PCI-DSS, HIPAA. We handle the framework mapping, evidence collection, and remediation guidance so you pass the first time.

🏗️

Security Architecture

Zero trust design, network segmentation, IAM strategy, and cloud security posture management. Build it right from the start.

Built by operators,
not consultants.

Arcline Security was founded by security practitioners who spent years on the offensive side — government, military, and private sector. We know how adversaries think because we've operated in those environments.

Every engagement is led by senior operators with real breach experience. No juniors running automated scans. No recycled templates. Every assessment is tailored to your specific threat model.
