What factors are contributing to the increased certificate revocation rate for Sectigo's DV SSL certificates in the last 30 days?

Introduction

The increased certificate revocation rate for Sectigo's DV SSL certificates in the last 30 days is a critical issue that demands immediate attention. This analysis will systematically identify, validate, and address the root cause while considering both short-term and long-term implications for our SSL certificate product line.

I'll approach this problem by first clarifying key details, ruling out external factors, and then diving deep into our product ecosystem. We'll break down the metric, gather relevant data, form hypotheses, and conduct a thorough root cause analysis. Finally, we'll develop a comprehensive plan to validate our findings and implement solutions.

Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a recent change in our certificate issuance process. Has there been any update to our validation or issuance systems in the past 60 days?

Why it matters: Recent system changes could directly impact certificate validity. Expected answer: Yes, there was a minor update to the validation system. Impact on approach: If confirmed, we'd prioritize investigating the update's effects.

• Given the specificity to DV SSL certificates, I'm wondering about our validation data sources. Have we changed any of our domain validation data providers recently?

Why it matters: Changes in data sources could lead to incorrect validations. Expected answer: No changes in providers, but there was an API update with one. Impact on approach: We'd focus on the API update and its potential consequences.

• Considering the increased revocation rate, I'm curious about our customer base. Has there been a significant shift in the types of customers acquiring DV SSL certificates in the last quarter?

Why it matters: New customer segments might have different usage patterns or requirements. Expected answer: There's been a 20% increase in small business customers. Impact on approach: We'd analyze how this customer shift might affect certificate usage and revocation.

• Thinking about external factors, I'm wondering if there have been any notable security incidents or policy changes in the SSL industry recently?

Why it matters: Industry events could prompt changes in certificate management practices. Expected answer: A major competitor experienced a security breach last month. Impact on approach: We'd investigate if this led to changes in our policies or customer behavior.
