Common Security Concerns

These are the risks developers face every day — and the ones most security tools ignore.

Running untrusted npm/pip packages

Every install is a gamble. Supply-chain attacks hide in dependencies you never audited. CoreLock flags suspicious package behavior before it escalates.

SSH keys and API tokens on your machine

Your laptop holds the keys to production. One compromised app and your credentials are exfiltrated. CoreLock monitors which processes access sensitive files.

Dev tools requesting excessive permissions

IDEs, Docker, terminal emulators — they all want camera, mic, and full disk access. CoreLock audits every permission so you know exactly what each tool can reach.

Compiling and running unknown codebases

Cloning repos and building locally is part of the job. CoreLock detects anomalous process spawning and network connections from freshly compiled binaries.

Features That Matter to Developers

CoreLock is not a generic antivirus. These are the capabilities that make a real difference for your work.

Process Behavior Analysis

AI-powered monitoring of every running process. Get alerted when a new binary makes unexpected network calls or accesses sensitive directories.

Privacy Permission Audit

See exactly which apps have camera, microphone, screen recording, and full disk access — including those sneaky Electron apps.

Code Signing Verification

Instantly verify if binaries are properly signed by Apple or their developers. Spot tampered executables before they run.

Network Connection Monitoring

Track every outbound connection from your machine. Know if a rogue process is phoning home to an unknown server.

One-Click Remediation

Found a threat? Fix it in one click. Revoke permissions, quarantine files, or kill processes without touching the terminal.

Recommended Plan

Most developers choose the Pro plan ($4.99/mo) for unlimited scans and real-time monitoring. The free tier (3 scans/day) is a solid way to start.

I installed a sketchy npm package and CoreLock flagged it within seconds — it was trying to read my .ssh directory. No other tool caught that.

Frequently Asked Questions

Does CoreLock slow down builds or compiles?

No. CoreLock monitors at the OS level, not the filesystem level. It watches process behavior and network connections without hooking into your build toolchain. Developers report zero measurable impact on compile times.

Can CoreLock detect supply-chain attacks in packages?

Yes. CoreLock uses behavioral analysis to flag when newly installed packages attempt suspicious actions — like reading SSH keys, accessing the keychain, or making unexpected network connections. This catches threats that static scanners miss.

Does it work with Docker and VMs?

CoreLock monitors your host macOS system. It will detect if Docker or a VM process makes unusual network connections or requests elevated permissions. It does not scan inside containers or VMs, which keeps its footprint minimal.

Is my data sent anywhere?

No. CoreLock processes everything locally on your machine. Scan results, process data, and permission audits never leave your device. This is a hard requirement for any developer tool, and we take it seriously.
