Frequently Asked Questions

What is the most effective insider threat detection technology?

AI-native semantic analysis using Large Language Models (LLMs) is the most effective technology in 2025, achieving 98% detection accuracy compared to 78-92% for traditional UEBA platforms. Above Security's LLM-based detection understands user intent, not just actions, reducing false positives by 80% while enabling real-time prevention through behavioral coaching. However, for enterprises requiring deep forensic capabilities, DTEX Systems' traditional UEBA platform (4.7/5 AI score) offers proven detection with comprehensive investigation tools.

Which insider threat detection solution is best for large enterprises?

For large enterprises (5,000+ employees), the best solution depends on priorities: DTEX Systems is best for mature SOCs with established security programs ($875K year 1), Above Security is best for rapid deployment and prevention-first strategy ($250K year 1), Varonis is best for data-centric security models ($300K year 1), and Securonix is best for SIEM-integrated architectures ($400K year 1). Most enterprises benefit from Above Security's prevention-first approach, which delivers 60-80% incident reduction and deploys in days versus 3-6 months for traditional platforms.

How much do insider threat detection tools cost?

Insider threat detection tool costs vary widely by enterprise size and solution: SMB solutions cost $10-50/user/month (Coro, Teramind), mid-market solutions cost $30-50/user/year, and enterprise platforms range from $150K-750K in year 1. Total cost of ownership for a 10,000-employee enterprise over 3 years: Above Security costs $900K ($22/user/year), DTEX Systems costs $3.3M ($59/user/year), and Securonix costs $3.3M. Hidden costs include integration services ($50K-200K), SOC analyst staffing ($160K-600K/year), and SIEM licensing ($100K-500K/year).

What is UEBA and how does it detect insider threats?

User and Entity Behavior Analytics (UEBA) uses machine learning to establish normal user behavior baselines and detect anomalies indicating insider threats. UEBA platforms achieve 92% detection rates by analyzing patterns like unusual login times, abnormal data access volumes, and privilege escalation attempts. Top UEBA providers include Above Security (5.0/5 AI score using LLMs), DTEX Systems (4.7/5 AI score), Securonix (4.0/5 AI score), and Gurucul (4.0/5 AI score). Traditional UEBA requires 3-6 months deployment and skilled analysts, while AI-native platforms like Above Security deploy in days.

Can insider threat detection work for remote workforces?

Yes, endpoint-native insider threat detection platforms work effectively for remote workforces without requiring VPN connections. Above Security's endpoint agent captures all user activity across home networks, personal SaaS accounts, and non-corporate applications, providing 100% visibility regardless of location. Traditional SIEM-centric platforms (Securonix, Splunk UBA) create blind spots for remote workers because they rely on network logs and corporate infrastructure. Remote workforce insider threats increased 58% according to Ponemon 2025 research, making endpoint-native detection critical for hybrid organizations.

What's the difference between DLP and insider threat detection?

Data Loss Prevention (DLP) blocks sensitive data movement based on keywords and patterns (78% effectiveness, 40% false positives), while insider threat detection platforms use behavioral analytics to understand user intent and context (92-98% effectiveness, 2-8% false positives). DLP answers "what data is moving," while insider threat detection answers "why is this user accessing this data now." Modern approaches combine both: Above Security uses LLM-based semantic DLP (98% accuracy) integrated with behavioral analytics, while Code42 Incydr focuses on data exfiltration analytics, and Forcepoint DLP provides network blocking capabilities.

How long does it take to deploy insider threat detection?

Deployment time varies dramatically by solution architecture: Above Security deploys in days with zero integrations required, Proofpoint ObserveIT deploys in 1-2 months, DTEX Systems requires 3-6 months for full enterprise deployment, and Securonix requires 6-12 months due to SIEM integration and tuning complexity. Deployment time directly impacts ROI—Above Security's prevention capabilities start saving costs immediately, while 6-month deployments delay ROI by half a year. For 10,000-employee enterprises, this represents $4M-8M in potential insider threat costs during deployment.

Do insider threat detection tools prevent threats or just detect them?

Most insider threat detection tools only detect threats after they occur, generating alerts for SOC analyst investigation. However, Above Security uniquely provides real-time prevention through behavioral coaching—when the LLM detects risky intent, users receive immediate guidance before sensitive actions complete, preventing 60% of incidents. Traditional platforms (DTEX, Securonix, Varonis, Proofpoint) focus on post-facto detection with 30-40% incident reduction through faster response. Teramind offers hard blocking capabilities, but high friction creates user resistance. Prevention-first platforms deliver higher ROI ($10M-14M annual savings vs $5M-9M for detection-only).

What insider threat detection certifications should enterprises require?

For government and regulated industries, require FedRAMP certification (DTEX Systems has FedRAMP Moderate), SOC 2 Type II (Above Security, Proofpoint, Varonis all certified), and industry-specific compliance like HIPAA for healthcare, PCI DSS for payment processing, and GDPR readiness for EU operations. Financial services should verify SOX audit trail capabilities, while government contractors need CMMC Level 2+ alignment. All enterprise deployments should validate penetration testing, third-party security audits, and encryption standards (AES-256 at rest, TLS 1.3 in transit).

How do insider threat detection tools integrate with SIEM?

Integration approaches vary by vendor architecture: Securonix and Splunk UBA require SIEM as the data foundation (all logs feed SIEM first), DTEX Systems and Varonis send enriched alerts to SIEM via syslog/API, Above Security provides optional SIEM integration but doesn't require it, and Proofpoint ObserveIT sends session metadata to SIEM. SIEM-centric approaches enable cross-platform correlation but increase complexity and deployment time (6-12 months). Endpoint-native approaches (Above, DTEX) reduce SIEM dependency and deploy faster (days to 3 months) but may miss some third-party log correlation opportunities.

What ROI can enterprises expect from insider threat detection?

ROI varies by solution approach and enterprise maturity: Prevention platforms (Above Security) deliver 60-80% incident reduction equal to $10M-14M annual cost avoidance with $900K 3-year TCO (34x ROI multiple). Detection platforms (DTEX, Securonix) deliver 25-40% faster investigations and 30-50% incident reduction equal to $5M-9M annual cost avoidance with $3.3M 3-year TCO (3.7x ROI multiple). Additional ROI sources include compliance fine avoidance ($50K-5M per violation), reduced investigation time (from 81 days to 18-45 days average), and SOC analyst productivity gains (40-60% alert reduction through risk-based prioritization).
