Is Your Network Spying on You?

Evil twin APs, ARP spoofing, DNS hijacking, and rogue certificates silently compromise millions of devices every day. OrbGuard detects these network-level threats before they can intercept your data.

Threat Detection

4 Network Attack Vectors We Neutralize

OrbGuard monitors your network connection in real time, detecting and blocking the most common attack techniques used on WiFi networks.

Evil Twin / Rogue AP Detection

Identifies fake WiFi networks that mimic legitimate ones to intercept your traffic.

MAC address spoofing detection
Signal strength anomaly analysis
SSID typosquatting identification
Known vendor OUI database (Cisco, TP-Link, Netgear, etc.)

ARP Spoofing & MITM Attacks

Real-time ARP table monitoring to detect man-in-the-middle attacks on local networks.

Continuous ARP table validation
Gateway impersonation detection
MAC anomaly correlation engine
Real-time packet inspection alerts

DNS Hijacking & Leak Detection

Validates that DNS queries are not being silently redirected to malicious resolvers.

DNS response integrity checks
DNS leak detection outside VPN tunnel
Encrypted DNS support (DoH/DoT)
Malicious domain blocking via threat feeds

SSL/TLS Certificate Verification

Detects unauthorized root certificates and MITM proxy interception in real time.

Rogue root certificate detection (MITM proxies)
Full certificate chain validation
Cipher suite strength analysis
SSL pinning verification for critical apps

WiFi Security Audit

Know Your Network's Weaknesses

OrbGuard performs a comprehensive audit of your WiFi connection, analyzing the security protocol, signal quality, channel interference, and connected devices to produce an overall network security score.

Real-World Threats

Attack Scenarios OrbGuard Prevents

These are not theoretical threats. These attacks happen every day in coffee shops, hotels, airports, and coworking spaces around the world.

Public CafeCritical

“Coffee Shop WiFi”

Attacker sets up "CoffeeShop_Free_WiFi" — an evil twin AP that mirrors the legitimate network. Unsuspecting users connect and all traffic is intercepted.

OrbGuard Detection

OrbGuard detects the unknown BSSID for the trusted SSID and alerts you before connecting. MAC vendor mismatch confirms rogue AP.

Hotel Business CenterHigh

“Hotel Network”

Compromised hotel router performs ARP spoofing to intercept banking and email traffic. Guests have no idea their sessions are being hijacked.

OrbGuard Detection

OrbGuard's real-time ARP table monitoring detects the gateway MAC address change and blocks the connection immediately.

Airport VIP LoungeCritical

“Airport Lounge”

A deauth attack forces all devices off the legitimate network. A fake AP with the same SSID captures reconnection credentials and session cookies.

OrbGuard Detection

OrbGuard detects the deauthentication frame flood pattern and prevents auto-reconnection to the spoofed AP.

Risk Engine

Evil Twin Detection Scoring

OrbGuard uses a weighted scoring system to calculate the probability that a network is malicious. Each indicator contributes a risk weight, and the cumulative score determines the threat level.

Unknown BSSID for trusted network
+0.4
Security downgrade detected
+0.3
Honeypot pattern match
+0.35
Deauth attack patterns
+0.4
THREAT LEVEL MATRIX
Critical>= 0.7
High>= 0.5
Medium>= 0.3
Low>= 0.15
Safe<0.15

Example: If an AP triggers "Unknown BSSID" (0.4) + "Security downgrade" (0.3) = 0.7, it is classified as Critical and auto-blocked.

FAQ

Frequently Asked Questions

How does OrbGuard detect Evil Twin access points?+
OrbGuard maintains a trusted network profile for each WiFi network you connect to. It stores the legitimate BSSID, MAC vendor, signal characteristics, and security configuration. When a new AP appears with the same SSID but different fingerprint, OrbGuard flags it immediately and prevents auto-connection.
Does network security scanning drain my battery?+
No. OrbGuard uses efficient passive monitoring that listens to network beacons and ARP frames without active scanning. The background process consumes less than 2% battery over a full day. Active WiFi audits only run when you request them.
Can OrbGuard protect me on public WiFi without a VPN?+
OrbGuard provides significant protection on public WiFi by detecting rogue APs, ARP spoofing, and DNS hijacking. However, for full encryption of your traffic, we recommend pairing OrbGuard with OrbVPN. Together, they provide defense-in-depth protection.
What is ARP spoofing and why is it dangerous?+
ARP spoofing is an attack where a malicious actor sends forged ARP messages on a local network, linking their MAC address with the IP of the default gateway. This causes all traffic to flow through the attacker, enabling them to read, modify, or block your data — including passwords, banking sessions, and private messages.
Does OrbGuard work on enterprise/corporate networks?+
Yes. OrbGuard is designed to work on both personal and enterprise networks. It integrates with MDM solutions (Intune, Jamf) and can export threat logs to SIEM platforms (Splunk, Elasticsearch, Microsoft Sentinel) for SOC teams to analyze.

Secure Your Network Connection

Don't let rogue access points, ARP spoofing, or DNS hijacking compromise your data. OrbGuard's network security module runs silently in the background, keeping you safe on every network.
