How we evaluate products
SecureDoor ranks products by real-world security value for Quebec homeowners — not by marketing copy, star ratings, or affiliate incentives.
Evidence hierarchy
We rank evidence sources in this order. Higher-ranked evidence outweighs lower-ranked evidence when sources conflict.
- E-01Independent forced-entry, drill, pick, or destructive testing
- E-02Locksmith, security professional, contractor, or trade review with specific product observations
- E-03Standards and certifications: ANSI/BHMA, UL 437, ANSI Z97.1, CPSC, ASTM, ULC
- E-04Canadian retailer availability and current pricing
- E-05Manufacturer specifications for dimensions, grade, thickness, screw length, warranty
Manufacturer claims never prove a product works by themselves.
What our rank labels mean
Evidence supports a real-world recommendation for Quebec homeowners.
Interesting design or approach, but independent proof is thin or Canadian availability is uncertain.
A common recommendation that has documented failure modes or specialist attack concerns.
Discontinued, unsupported, unavailable in Quebec, or has documented critical failures.
How we describe security claims
We say
- reinforces
- delays
- increases resistance
- reduces easy opportunity
- requires sustained effort
We don't say
- absolute-proof claims
- guaranteed-entry claims
- ballistic claims
- impossible-to-pick claims
Security products delay and resist attacks. They do not guarantee outcomes. We describe what the evidence shows.
The Quebec rule
Every recommendation for Quebec homeowners is checked for: Canadian retail availability, French/Quebec language support where relevant, winter performance, older-home compatibility, and egress impact. Products that are US-only, discontinued, or explicitly unavailable in Quebec are marked accordingly and not ranked.
