Quick Comparison

Detailed Comparison

1. Specialized Knowledge vs. General Intelligence

ISMS Copilot: Compliance Specialist with Framework Knowledge Injection

ISMS Copilot v2.5 (February 2025) uses dynamic framework knowledge injection to nearly eliminate hallucinations:

• Framework detection: Automatically detects when you mention ISO 27001, SOC 2, GDPR, HIPAA, CCPA, NIS 2, DORA, ISO 42001, ISO 27701, or EU AI Act

• Knowledge injection: Provides AI with verified framework knowledge before it responds

• Grounded responses: AI answers based on actual framework knowledge, not probabilistic guessing

• 10 frameworks supported: ISO 27001:2022, ISO 42001:2023, ISO 27701:2025, SOC 2, HIPAA, GDPR, CCPA, NIS 2, DORA, EU AI Act

• Scope limitation: Stays focused on ISMS and compliance—won't try to answer unrelated questions

ChatGPT: Generalist AI

ChatGPT is trained on broad internet content for versatile use across domains:

• Training foundation: Massive dataset covering nearly all human knowledge domains

• Capabilities: Writing, coding, research, creative tasks, problem-solving, conversation

• Broad knowledge: Can discuss almost any topic but lacks deep specialization

• Advanced features: Web search, image analysis, code execution, voice mode

Verdict: For compliance work requiring accuracy and audit-ready outputs, ISMS Copilot's dynamic framework knowledge injection (v2.5) provides dramatically more reliable guidance by grounding AI responses in verified framework knowledge. For general tasks, creative writing, or coding, ChatGPT excels.

2. Data Privacy and Security

ISMS Copilot: Privacy-First Architecture

Built for handling sensitive client compliance data:

• Zero training on user data: Your conversations, documents, and client information are never used to train AI models

• EU data residency: All data stored in Frankfurt, Germany (AWS EU region) with GDPR compliance

• End-to-end encryption: AES-256 encryption at rest; TLS 1.3 in transit

• User-controlled retention: Set data retention from 1 day to 7 years or keep forever

• Workspace isolation: Separate workspaces prevent mixing client data

• No cross-customer sharing: Your data is never visible to other users

ChatGPT: General Platform Privacy

ChatGPT's privacy model varies by tier and configuration:

• Free tier: Conversations may be used to train future models (though users can opt out)

• ChatGPT Plus/Team: Can disable training on your data in settings

• ChatGPT Enterprise: Guaranteed no training on business data

• Data storage: US-based infrastructure (not EU-specific)

• Retention: Conversations stored indefinitely unless manually deleted

• Memory feature: Can remember information across conversations (requires manual management)

Verdict: ISMS Copilot provides stronger privacy guarantees by default, with EU data residency and zero training on user data. ChatGPT requires enterprise plans and manual configuration to achieve similar privacy levels.

3. Accuracy and Hallucination Risk

ISMS Copilot: Nearly Eliminates Hallucination for Framework Questions

Dynamic framework knowledge injection (v2.5) dramatically reduces hallucination risk:

• Framework knowledge injection: AI receives verified framework knowledge before answering, preventing fabricated control numbers and requirements

• Reliable detection: Regex-based framework detection (not AI-based) ensures 100% reliability when frameworks are mentioned

• 10 frameworks supported: ISO 27001:2022, ISO 42001:2023, ISO 27701:2025, SOC 2, HIPAA, GDPR, CCPA, NIS 2, DORA, EU AI Act

• Uncertainty acknowledgment: Explicitly warns when information should be verified

• Copyright protection: Won't reproduce copyrighted standards (avoiding fabricated standard text)

• Scope constraints: Stays within compliance domain instead of guessing on unfamiliar topics

ChatGPT: Higher Risk for Specialized Topics

General training increases hallucination risk for niche domains:

• Broad but shallow: Knows about many frameworks but lacks depth in any single one

• Pattern-based generation: May fabricate plausible-sounding control numbers or requirements

• Version confusion: Can mix ISO 27001:2013 and 2022 controls without clear differentiation

• Overconfidence: Presents information authoritatively even when uncertain

Verdict: For compliance-critical work requiring accuracy, ISMS Copilot's framework knowledge injection (v2.5) nearly eliminates hallucination risk for supported frameworks. ChatGPT requires extensive verification and fact-checking for compliance outputs because it relies on internal knowledge and web search.

4. Document Analysis and File Support

ISMS Copilot: Compliance Document Focus

Designed for analyzing compliance documentation:

• Supported formats: PDF, DOC, DOCX, XLS, XLSX, CSV, JSON, TXT

• File size limit: 10 MB per file

• Analysis types: Gap analysis, GDPR compliance checks, policy reviews, risk assessment evaluation

• Use cases: Upload existing policies for compliance recommendations, analyze audit reports, review risk assessments

ChatGPT: Multimodal Capabilities

Advanced document and media processing:

• Supported formats: PDF, DOCX, images (JPG, PNG), spreadsheets

• File size limits: Vary by plan; generally larger than ISMS Copilot

• Advanced features: Image analysis, diagram interpretation, code generation from visuals

• Use cases: Extract text from images, analyze charts, process multi-page documents

Verdict: ISMS Copilot provides better compliance-specific document analysis (gap analysis, control mapping). ChatGPT offers broader file format support and multimodal capabilities.

5. Workspace and Project Organization

ISMS Copilot: Client-Focused Organization

Built for managing multiple compliance projects:

• Workspaces: Create separate workspaces for different clients, frameworks, or projects

• Custom instructions: Each workspace can have tailored instructions (e.g., "This client is a 50-person SaaS company in healthcare")

• Isolated history: Conversations and files don't mix between workspaces

• Personas: Choose AI roles (Default, Implementer, Auditor, Consultant) for different tasks

ChatGPT: Conversation-Based Organization

Simpler conversation management:

• Conversation threads: Each conversation is separate but not explicitly project-organized

• Memory feature: Can remember preferences across conversations (requires manual management)

• Custom instructions: Global custom instructions apply to all conversations

• Search: Search chat history to find past conversations

Verdict: ISMS Copilot provides superior project organization for multi-client compliance work through isolated workspaces. ChatGPT uses simpler conversation-based organization better suited for individual use.

6. Pricing and Plans

Quick Buying Guide

Not sure which way to go? Here's the straightforward answer.

Pick ISMS Copilot if you answer yes to any of these:

• You're implementing ISO 27001, SOC 2, GDPR, or similar frameworks and need answers you can trust without fact-checking every control number

• You handle client compliance data and need guaranteed workspace isolation so projects never mix

• EU data residency isn't optional—it's a requirement for your work or your clients

ChatGPT is enough if:

• Compliance work is occasional for you—not your day job

• You need an AI for everything: writing, coding, research, images, and compliance is just one piece

• You're comfortable configuring privacy settings yourself and verifying every compliance output manually

The three deal-breakers

If any of these apply to your situation, a general AI like ChatGPT is the wrong choice:

1. You can't afford hallucinated control numbers. ChatGPT will confidently invent ISO 27001 control references that don't exist. ISMS Copilot's framework knowledge injection prevents this by grounding responses in verified framework knowledge.

2. Client confidentiality is non-negotiable. ChatGPT has no workspace isolation—your conversations live in one long list. ISMS Copilot keeps each client in a separate workspace with its own history, files, and custom instructions.

3. GDPR requires EU data storage. ChatGPT runs on US infrastructure. ISMS Copilot stores everything in Frankfurt, Germany, and never trains on your data—no configuration required.
