Personal Laptop Security Monitor: Detect Unauthorized Remote Access & Suspicious Activity.

Niche Market Opportunity: Unauthorized Remote Access Monitoring & Idle Activity Security for Non-Technical Users.

Analysis: The Reddit post and its comments clearly show that many everyday computer users are worried and confused about unauthorized remote access and unexplained activity on their devices. The user's panic ("Was I hacked?") and the community's advice (check Remote Desktop, TeamViewer, AnyDesk) highlight a real need for a solution that simplifies the detection, monitoring, and understanding of such events. This goes beyond what standard antivirus software typically offers, as it may not focus specifically on or clearly report the misuse of legitimate remote access tools or suspicious idle-time behavior.

SaaS Opportunity: A specialized SaaS product designed to provide peace of mind by monitoring for unauthorized remote access and unusual activity when the user is away from their computer.

Product Form: "PC Guardian" (or a similar name emphasizing security and oversight)

• Type: Desktop Client Software (initially for Windows, with potential for macOS later) with a cloud-backed dashboard/reporting component.
• Core Features:
  1. Comprehensive Remote Access Monitoring:
     • Detects and logs activity from known remote access tools (e.g., Windows RDP, TeamViewer, AnyDesk, Chrome Remote Desktop, VNC, etc.).
     • Alerts on new remote access software installations.
     • Logs connection times, duration, and originating IP addresses (where possible).
  2. Idle-Time Activity Detection:
     • Monitors for mouse movements, keyboard input, application launches, and significant network activity when the system is locked, the lid is closed, or after a user-defined period of inactivity.
     • Provides context, e.g., "Microsoft Edge was launched at 3:00 AM while the screen was locked."
  3. Simplified Event Logging & Reporting:
     • A human-readable activity log, highlighting events that occurred during user absence or idle periods.
     • Dashboard summarizing key events, active remote access tools, and security recommendations.
     • Option to "tag" sessions or activity as "expected" or "suspicious" for user records.
  4. User-Friendly Alerts & Notifications:
     • Real-time alerts (desktop notifications, optional email/mobile app) for:
       • Remote connections initiated.
       • Unexpected activity during idle times.
       • Installation of new remote access software.
  5. Basic Security Configuration Guidance:
     • Checks for common insecure configurations (e.g., RDP enabled with weak password policies) and provides simple, actionable advice.
     • Easy links to disable common remote access features if not needed.

Target Audience: Non-technical home users, freelancers, and small business owners who are concerned about privacy and unauthorized access but find existing security tools too complex or not focused on this specific threat vector.
