Built to bridge the security gap.

Rhentech was founded on a straightforward observation: mid-market businesses face the same cyber threats as large enterprises, but rarely have access to the same quality of expertise. Most are stuck choosing between expensive Big Four engagements and underqualified local providers.

We built Rhentech to be the alternative: a consultancy staffed entirely by senior practitioners who have led security functions, responded to real incidents, and advised boards. No graduate programmes. No bench consultants learning on your time.

Every engagement is led by someone with the experience to make judgement calls under pressure, because in cybersecurity, that is what separates a good outcome from a catastrophic one.

  • Senior-only

    Every engagement is led and delivered by a senior consultant

  • Audit-first

    We assess before we prescribe: no cookie-cutter solutions

  • South African regulated

    Deep expertise across POPIA, CIPC, SARS, NCA frameworks

  • AI-augmented

    Machine-speed threat detection, human-led decision making

What sets us apart

Five principles that shape every engagement, and every recommendation we make.

  • Senior-led delivery

    No junior staff. No graduates learning on your account. Every engagement is led and delivered by a consultant with deep, hands-on experience in cybersecurity and IT operations.

  • AI-powered security operations

    We combine machine-speed threat detection with human-led analysis. AI handles the volume; our consultants handle the judgement. The result is faster response times and fewer false positives.

  • Audit-first methodology

    We never prescribe solutions without first understanding your risk landscape. Every client relationship starts with an honest assessment, so recommendations are grounded in evidence, not assumptions.

  • Direct access, no account managers

    You speak to the person doing the work. No layers of project management, no handoffs, no "I'll check with the team." Your consultant owns the engagement from start to finish.

  • Long-term relational depth

    Through long-term managed engagements we come to know your operations, your people, and your business in a way no audit can replicate. That depth is what makes our strategic recommendations land. It's also what we're here for.

Accreditations and frameworks

Our methodology is aligned with the frameworks that matter to regulated South African businesses.

  • CIS Controls

    Center for Internet Security framework

  • ISO 27001 aligned

  • NIST CSF aligned

    Data protection and privacy

Understand. Protect. Monitor.

A proven methodology that moves from understanding your risk to actively managing it.

  1. Risk assessment

    Understand

    We begin with an honest, thorough assessment of your current security posture: identifying vulnerabilities, mapping your attack surface, and quantifying risk in terms the board can act on.

  2. Implement controls

    Protect

    Based on the assessment, we design and implement proportionate security controls: technical, procedural, and organisational. Every recommendation is prioritised by risk impact and business value.

  3. Ongoing managed security

    Monitor

    Security is not a one-off project. We provide continuous monitoring, threat detection, and incident response, combining AI-powered automation with senior human oversight around the clock.
