Professional course · OISI-3 Strengthen communication, internal branding and security culture so a small security function can create meaningful influence across a large organisation. Who should attend Course purpose Effective communication, strategic branding and a cohesive organisational culture are central to how security is understood and supported across a business. This intensive course gives security departments practical tools to elevate their internal communication, strengthen their identity and create a culture where security is understood as a shared responsibility. Participants explore how a small security function can influence a much larger workforce consistently through clear messages, visible leadership, useful engagement and purposeful collaboration. Course focus Operational outcomes A clearer internal security communication approach Stronger security department identity and visibility Practical methods for influencing larger workforces More connected security culture activity Better use of collaboration and diversity Greater organisational impact from security resources Influence in practice A 10–20-person security function is used as an example only, not as a universal staffing benchmark. A 20-person function represents 2% of the workforce. That is 50 workforce members per security professional. At 10 people, it is 1%, or 100 per professional. A 20-person function represents 0.5% of the workforce. That is 200 workforce members per security professional. At 10 people, it is 0.25%, or 400 per professional. The department creates influence through communication, trusted identity, repeatable engagement and shared security culture. Practical application The course connects the security department’s internal identity with the behaviours, relationships and communication routes that create influence across the organisation.
