Recently, I detailed how I used a variety of Ai services with the same prompt to compare the generated results. You can read that initial article here:
Testing the differences between AI services
The next step in this journey is now to start comparing them. For that I have used Microsoft 365 Copilot with GPT5 enabled. Here’s a concise summary of the key differences across the seven CIAOPS posts:
1. Audience & Tone
- Aug 28 (ChatGPT DR): Short, practical overview for SMB IT/MSPs.
- Aug 29 (Copilot Researcher): Formal, report‑style for CIO/CFO decision‑makers.
- Aug 30 (Copilot Studio GPT‑5): Practitioner‑centric with actionable steps.
- Aug 31 (Deepseek DR): Conceptual, explains “de‑perimeterization.”
- Sep 1 (Gemini DR): Strategic, cost‑focused for board/C‑suite.
- Sep 2 (ChatGPT): Feature‑inventory framing for non‑technical buyers.
- Sep 3 (M365 Copilot GPT): Visionary/philosophical capstone on Zero Trust.
2. Unique Angle
- Aug 28: Emphasizes App Proxy and host firewall as VPN/WAF alternatives.
- Aug 29: Compares traditional firewall roles vs. modern limits; cost lens.
- Aug 30: Provides a hardening checklist and “when you still need a firewall.”
- Aug 31: Maps NGFW functions to M365 features; identity/data as perimeter.
- Sep 1: Argues high‑end firewalls are financially inefficient for SMBs.
- Sep 2: Highlights advanced security controls now built into M365 BP.
- Sep 3: States perimeter is no longer the main control—identity/device/app is.
3. Depth & Practicality
- Most actionable: Aug 30 (step‑by‑step baseline + decision criteria).
- Most strategic: Sep 1 and Aug 29 (budget and governance framing).
- Most conceptual: Aug 31 and Sep 3 (Zero Trust philosophy).
- Most feature‑focused: Sep 2 (inventory of built‑in controls).
Here’s a comparison table summarizing the key differences across the seven CIAOPS posts
| Post & Date | Audience & Tone | Unique Angle | Depth & Practicality |
|---|---|---|---|
| Aug 28 – ChatGPT (Deep Research) | SMB IT / MSPs; concise | App Proxy & host firewall as VPN/WAF alternatives | Moderate detail; quick read |
| Aug 29 – Copilot Researcher | CIO/CFO; formal report | Traditional firewall roles vs. modern limits; cost analysis | High-level strategy; structured |
| Aug 30 – Copilot Studio (GPT-5) | Admins/MSPs; hands-on | Hardening checklist + “when you still need a firewall” | Most actionable; step-by-step |
| Aug 31 – Deepseek (Deep Research) | SMB leaders; conceptual | Identity/data as the new perimeter; function mapping | Conceptual depth; less prescriptive |
| Sep 1 – Gemini (Deep Research) | Board/C-suite; strategic | Financial inefficiency of high-end firewalls for SMBs | Strategic recommendation |
| Sep 2 – ChatGPT | Non-technical buyers | Inventory of advanced security controls in M365 BP | Feature-focused; overview |
| Sep 3 – M365 Copilot (GPT) | Vision/strategy leaders | “Perimeter is no longer the main control” (Zero Trust) | Philosophical capstone |
