Understanding Audit Grades

Every website is scored out of 1,000 points across 12 categories. All grades represent a valid, authenticated certificate — the grade indicates the quality level achieved.

A+
Outstanding
950 – 1,000
Exceptional. Best-in-class security, performance, and compliance across all categories.
A
Excellent
900 – 949
Excellent posture with only minor, low-risk findings. Well above industry average.
B
Good
800 – 899
Solid fundamentals in place. A few areas could be strengthened with moderate effort.
C
Fair
700 – 799
Adequate baseline but notable gaps exist. Improvement recommended before issues compound.
D
Poor
550 – 699
Significant weaknesses found. Immediate attention needed to address key security and compliance gaps.
E
Critical
0 – 549
Critical issues present. Urgent remediation required to protect users and meet basic standards.

How Scoring Works

Our comprehensive audit evaluates your website across 12 weighted categories totalling 1,000 points. Each category is scored as a percentage of its weight — penalties are deducted for failed checks based on their severity.

  • Transport Security (140)
  • Security Headers (120)
  • Legal & Compliance (140)
  • Information Exposure (110)
  • Authentication & Forms (80)
  • Client-Side Security (70)
  • Performance (70)
  • DNS & Email (60)
  • Cookie Security (60)
  • SEO & Accessibility (50)
  • Reliability (50)
  • Progressive Web App (50)

Each individual check is classified by severity — Critical, High, Medium, Low, or Informational — with proportionate penalty values. A higher score means fewer issues and better protection for your users.
