Security Commitment

Herbst Group maintains 42 enforced critical controls governing information security, data protection, and AI governance. These controls are locked by CEO authority and cannot be bypassed by any team member, workflow, or automation.

Our security program follows defense-in-depth principles: multiple independent layers of protection ensure that no single failure compromises client data. We conduct continuous monitoring, maintain formal incident response procedures, and integrate lessons learned from every security event into our policies.

Data Protection

POPIA: Registered with Information Regulator
Information Officer Willem Dieter Herbst (CEO) and Deputy Information Officer Tiaan Keyser (CAO) registered with the Information Regulator. Registration No. 2026-001668, issued 8 February 2026.

Our published privacy policy covers five Herbst Group entities and was approved by Board Resolution on 11 November 2025.

Your rights under POPIA

We maintain documented procedures for data subject requests including access, correction, deletion, and objection. Contact our Deputy Information Officer at tiaan@herbstteam.com.

Cross-border safeguards

Where client data is processed outside South Africa, we maintain Data Processing Agreements with Standard Contractual Clauses covering EU data flows. We have an option for SA-resident data stewardship: client data can be hosted on encrypted infrastructure in Johannesburg, POPIA-bound by design, as we continue pursuing ISO 27001.

Privacy-first analytics

We use Plausible Analytics, which collects no personal data and sets no cookies. No consent banner is required because no tracking occurs.

Client data isolation

Each client's data is isolated in separate database tenants. No client data may be used to enrich, benchmark, or cross-reference another client's engagement.

Responsible AI Use

Abstract neural network visualization representing responsible AI governance

Herbst Group uses Anthropic Claude AI via the commercial API to enhance pharmaceutical consulting services, including research synthesis, report generation, and data interpretation. Licensed third-party data assets that inform this work are governed by controls that ringfence each dataset within the terms of its licence, keeping it isolated from other engagements and never repurposed beyond the scope for which it was licensed.

Controls in place

  • All AI-generated content is reviewed by qualified consultants before client delivery
  • No clinical decision-making is delegated to AI
  • Client data is not used for model training under our commercial API terms with Anthropic
  • Claude is accessed only through the Anthropic API, governed by a signed Data Processing Addendum
  • Human-in-the-loop oversight on all client deliverables
  • Strict data fabrication prevention controls (CEO-enforced)

Legal framework

  • Copyright indemnity for AI-generated outputs
  • Full ownership of all Claude-generated content retained by Herbst Group

Pharmaceutical AI standards

  • Aligned with NIST AI RMF principles
  • Implementing GAMP 5 principles for AI/ML in regulated environments
  • AI contribution documented in every report methodology section

Clients are informed when AI assists in analysis. We document the role of AI in our deliverables and welcome questions about our AI governance practices.

Infrastructure & Encryption

Data in transit

TLS 1.3 with HSTS at 1-year max-age. HSTS preload submitted. Comprehensive CSP, X-Frame-Options DENY, Permissions-Policy restricting camera, microphone, and geolocation.

Data at rest

All endpoint devices encrypted with FileVault (AES-256). Backups are encrypted and stored on a daily schedule with formally defined Recovery Time and Recovery Point Objectives.

Data residency

Our data infrastructure is located in South Africa. On a client-elected basis, Herbst Group houses client data and our intelligence frameworks on our own South African server, under our control and built around POPIA principles, so that data remains resident within South Africa. Any remaining cross-border data flows are documented and covered by Data Processing Agreements.

Environmental Commitment

As a digital-first professional services firm, our environmental footprint is primarily cloud infrastructure and business travel. We measure what matters and set honest targets.

Carbon Offset Programme

Herbst Group retired 20 tCO2e of verified carbon credits in February 2026 via the Sun Exchange solar project in South Africa, registered with Credible Carbon (RRE_ZLVYE9YA). This offsets 133% of our estimated annual business travel emissions. We follow an Avoid-Reduce-Offset hierarchy aligned with the GHG Protocol (Scope 3, Category 6) and target a 10% year-on-year reduction in travel emissions.

Community Reforestation Partnership

Herbst Group is a monthly donor to the Greenpop Foundation NPC (NPO 151-411, PBO 930050622), supporting the Forests For Life programme. We fund the planting of 16 indigenous trees per month in community-centred forest restoration sites across South Africa. Each tree is GPS-tracked and verified quarterly. Partnership MOU signed 5 March 2026. First donation made the same day.
