What Chef Got Wrong. Fact-checking Their "Chef vs Puppet" Comparison Page

Intro 

In November 2025, Progress Chef outlined their plans to deprecate Chef Infra Server; which will reach end of life effective November 30, 2026. For Infra Server users, this means you have an opportunity to evaluate your infrastructure solutions to make sure it meets enforces internal or regulatory compliance policies, lets you manage infra everywhere it lives today, and sets you on the right path for the future.  

The Puppet Enterprise platform is not the same infrastructure management software from years past, and it is not used as the foundation of most of the comparisons discussed in the Chef 360 vs. Puppet content on the chef.io website. Since the launching the Puppet Enterprise platform, we have focused on ensuring customers have compliance enforcement and security built into their infrastructure management with a unified solution that integrates with tools your organization is already using and have no intentions of changing. Tools like Service Now, Datadog, Nessus, Prometheus, Grafana, Claude, and more.   

As you evaluate options, and the best solution for managing infrastructure governance and compliance enforcement, we wanted to make sure you have the correct information before making a purchasing decision. For starters, it’s critical you are comparing apples to apples vs. apples to oranges. And the best comparable infrastructure solution to Chef 360 is Puppet Enterprise Advanced.  

What Chef's Page Actually Says 

Below is a summary of the chart and FAQ claims found on the Progress Chef website.

Fact Check With Puppet Enterprise Advanced 

Chef Claims:

"Masters, DBs have to be maintained in addition to HA overhead"

Verdict: True. 

However, this is a deliberate trade-off, not a capability gap.

Why?

Puppet Enterprise Advanced customers are most often in highly regulated industries and prefer to maintain direct control over infrastructure and data. Therefore, this is not a capability Puppet lacks, it’s a choice to invest engineering resources to meet the needs of our customers.  

Chef Claims:

"Needs separate paths and script glue" to run agent & agentless workflows.

Verdict: False.

Also misleading because Chef has 2 different definitions of agentless. Agentless orchestrations via Courier requires interpreter skills to be installed on a node, which is done during node enrollment. Chef Infra Client also has an “agentless mode” which can be used to execute a client run on nodes without a client installed.  

Why?

Puppet Edge, which includes Ansible Playbook Runner, executes directly in the Puppet Enterprise Advanced GUI and run on agentless nodes – any network device.  

Puppet Enterprise console allows you to run both agent and agentless tasks or plans without the need for separate paths and script glue.

Chef Claims:

Rollout consistency and auditability: "Manual waves, inconsistent behavior, ad-hoc rollbacks"

Verdict: False.

• Impact Analysis acts as a safety gate, predicating impact of a code change before it is deployed.  
• Continuous compliance with automatic drift remediation maintains configuration consistency 
• Every change made by the run to restore the desired configuration state, are documented and timestamped for 24/7 audit readiness. 

Why?

Helping teams understand the blast radius of a code change before deployment is the fundamental job of Impact Analysis – included in the Advanced solution and accessed through the GUI. In addition, Puppet keeps you continuously in compliance by automatically running checks across the estate every 30 minutes—which can be adjusted to fit your needs—and corrects drift. 

Define. Detect. Remediate. Prove.

Chef Claims:

"Controls validated post-change, evidence assembled later"

Verdict: False.

• Compliance validation is built directly into the desired-state configuration controls rather than being treated as a separate post-deployment task 
• CIS Benchmarks and DISA STIG alignment is defined from the start, selected from a library, and enforced automatically with Security Compliance Enforcement.  
• As regulations change, the configuration can be updated.  
• Impact Analysis allows you to catch compliance collisions BEFORE deployment by automatically generating a clean, visual delta report to provide to SecOps and compliance leaders to ensure alignment on risk.

Why?

Security Compliance Enforcement (SCE) enforces continuously. There are no manual steps required to kick off a scan and run intervals can be customized based on business requirements.

Chef Claims:

"Approvals in one place, logs in another, evidence manually rebuilt" FAQ: "manual upkeep," "manual processes slow response"

Verdict: Confirmed False.

• Puppet Enterprise console handles role-based approvals and orchestrated job execution in one place; there's no separate approval system that needs reconciling with what actually ran. 
• Every agent run, catalog application, and change event lands in PuppetDB. This can be queried with ISO 42001 certified Infra Assistant or using PQL.  
• Security Compliance Enforcement (SCE) enforces CIS/DISA STIG controls and produces compliance evidence as part of normal operation. This is not something that is “stitched together” after the fact.  

Why?

PuppetDB + PE console are a single reporting surface; Same information from SCE above also applies.

Chef Claims:

FAQ: "legacy deployments may increase costs" 

Verdict: Unsourced

Why?

This is an unsourced, biased opinion.  

It's Not Just The Landing Page 

There are several claims throughout the chef.io website with various claims. Such as, "Puppet was built for predictability. Chef is built for speed, security and scale." implying Puppet lacks speed, security, and scale. In reality, the largest Puppet deployments are with customers in regulated industries like financial services, government, retail, software and IT services, and more. 

Ambit Energy uses Puppet to help achieve speeds that were 1200X faster with Puppet Enterprise. Puppet was built for compliance enforcement and infrastructure governance when you need to manage massive environments that cross jurisdictional boundaries around the world.  

Walmart is using Puppet to control drift and stated, “[Puppet]'s doing that job fantastically well across multiple OS platforms, across huge geographic distances – stores thousands of miles away are using the same infrastructure – and it’s all working." 

What the Chef.io Page Never Mentions 

When compared their Chef 360 to Perforce Puppet’s capabilities (which they refer to as the Puppet Stack), they weren’t comparing one enterprise platform to another. Puppet Enterprise Platform has additional advanced capabilities that were not even mentioned – like ISO 42001 Certified Infra Assistant and Infra Assistant: code assist.  

ISO 42001 Certification is the world’s first AI management system standard that helps ensure responsible development and use of AI systems. It’s a trust signal that is quickly becoming a requirement for procurement in regulated industries because it addresses unique AI challenges like ethical considerations, transparency, and continuous learning. Leveraging AI is more of “need to have” to meet today’s demands. Responsible AI is a priority at Perforce, which is why they were among a small percentage of organizations reaching this certification in February, 2026 for 7 unique AI solutions – including Puppet Infra Assistant and code assist.  

In addition, the newly launched Perforce Agentic Gateway is a free, model-agnostic MCP gateway that allows you to connect any Perforce MCP – Puppet included – and outside MCP’s in one simple interface to create customized dashboards that save token usage.  

Where Chef 360 Has a Fair Point

To be fair, Chef 360's SaaS control plane is legitimate option for teams wanting Chef to maintain and control their infrastructure. For some organizations, this may be an ideal fit.  

They even have early access availability for their own AI assistant called Chef Opsmith. However, at the time of publishing this blog, there is no mention of ISO certification for Chef Opsmith.

The Corrected Table

Prepare Today for Tomorrow's Governance Demands

If the words “Infrastructure Audit” cause the hair on your neck to stand up or your heart to race, it is worth considering your options with Chef Infra Server reaching end of life status in 2026. The way organizations approach compliance — internal or regulatory — will continue to lean toward governance over larger hybrid estates. For Infrastructure Leaders, that means you need a solution that scales globally, accommodates bare metal, VMs, and containers, in global environments that cross jurisdictional boundaries.
