Course formats
What each OPSEC course covers: one, two or three days.
Operational security tradecraft for investigators running online and covert work. The course teaches teams how to find and mitigate data leaks from their devices, sustain anonymity, and build a secure working environment that protects both the investigator and the admissibility of evidence. This is operational security training for investigators and OSINT practitioners — not a military compliance briefing. For organisation-level hardening, see our cybersecurity consulting; for OPSEC applied to live casework, the law-enforcement use case.
Each format builds on the one before. Every topic is scoped to lawful, defensible tradecraft.

Request dates and a proposalHow a programme is built
From threat model to operational discipline.
Step 1
Scope & threat model
We define the operational context, adversary profile, lawful boundaries, and the security outcomes the team must achieve.

Format & modules
We choose the one-, two- or three-day format with you and adapt its modules to your mission profile, tooling, and time available.
Step 3
Hands-on delivery
Practitioner-led sessions with realistic scenarios, device drills, and tradecraft exercises — in person, or online on request.
Step 4
Post-training support
Reference materials, optional refreshers, and follow-on advisory to embed OPSEC discipline in day-to-day operations.

OPSEC — operational security — training teaches investigators and analysts to protect their identity, devices, and communications while working. Next Sight's one-day course covers online OPSEC in online investigations: anonymity and pseudonymity, secure communication, VPNs and proxies, browser and device security, data encryption, digital footprint management, and incident response. The two-day course adds basic offline OPSEC, and the three-day course the basics of countersurveillance.
Law enforcement, private investigators, intelligence units, corporate security teams, investigative journalists, and government investigators — any team whose online research could expose its people or organisation to adversarial attention.
Military and government OPSEC awareness programmes focus on policy compliance. Next Sight's OPSEC training is operational: it teaches investigators and OSINT practitioners to protect their identity, devices, communications, and casework online — anonymity and pseudonymity, secure communications, browser and device security, digital footprint management, and incident response — with case studies and hands-on drills.
In person, or online on request: instructor-led sessions in English for groups of 10 to 25, in formats of one, two or three days, with case studies and practical exercises calibrated to your operational environment.
