Google, Mozilla, and Apple choosing to no longer support Entrust as a publicly trusted certificate authority

Google, Mozilla, and Apple have all decided to stop trusting Entrust’s publicly issued certificates after specific cutoff dates, due to long-standing compliance issues.

Why the Distrust?

Browsers depend on Certificate Authorities (CAs) to uphold stringent security and industry standards. Entrust repeatedly failed to comply—examples include delay in revoking misissued certificates, poor incident reporting, and administrative errors. This pattern of “compliance failures” led browsers to lose confidence in Entrust’s ability to act responsibly and transparently.

Organization	Affected Certificates	Cutoff Date	Notes
Google Chrome	TLS certificates with Signed Certificate Timestamp (SCT) post-issue date	November 11, 2024	Entrust roots not trusted in Chrome Root Program for certs issued after Oct 31, 2024 (Entrust, DigiCert, The Wall Street Journal, Cloudflare Docs, The Cloudflare Blog, Enterprise Security Tech)
Apple (Safari and Root Store)	TLS, S/MIME, Timestamping, VMCs issued after specific date	November 15, 2024	Doesn’t affect certs issued on or before that date; broader certificate types impacted (Entrust, DigiCert)
Mozilla Firefox	TLS certificates via Entrust roots	November 30, 2024	Distrust due to repeated compliance issues and insufficient corrective action (Google Groups, Encryption Consulting, DigiCert, Wikipedia)

What This Means for Users

• Old Entrust Certificates Still Valid – Certificates issued on or before the cutoff dates will remain trusted until their natural expiry.

• New Entrust Certificates Likely to Fail – Certificates issued after the specified cutoff dates will trigger browser warnings or outright blockage.

For example:

• Chrome rejects SCT-dated Entrust certificates after Nov 11, 2024.

• Apple’s platforms (like Safari) reject Entrust TLS/S‑MIME certs issued after Nov 15, 2024.

• Firefox stops trusting Entrust-issued TLS certs from Nov 30, 2024. 

Entrust’s Reaction & Alternatives

Entrust publicly announced that certificates issued prior to the cutoff remain valid, and they’re working on fixing their internal processes—such as adding linting tools, establishing a change control board, and bolstering audit transparency.

Meanwhile, they’ve partnered with SSL.com to issue new certificates on Entrust’s behalf—that still rely on SSL.com roots to maintain browser trust. Cloudflare even enabled SSL.com certificates to ease migration.

--> Certificates issued before 31/10/2024 will remain valid. Certificate issued after 31/10/2024 will be no longer trusted by Google.

--> "Entrust made no moves to revoke or replace the affected certificates."

Summary

Google, Mozilla, and Apple have withdrawn trust in Entrust’s public roots, but each did so at slightly different times and with varying scopes:

• Chrome/Google — bye to Entrust-issued TLS certs after Nov 11, 2024.

• Apple/Safari — blocks wider certificate types (TLS, S/MIME, VMCs) after Nov 15, 2024.

• Firefox/Mozilla — distrust kicks in end-Nov 2024.

Entrust’s existing certificates issued before those dates remain valid. For new issuance, organizations should migrate to trusted alternatives—like SSL.com or DigiCert—to avoid browser compatibility issues.

Virtual Cloud Network - Networking Constructs

 

Simple Architecture:

Oracle Cloud Infrastructure (OCI) – VCN Networking Constructs

In Oracle Cloud Infrastructure (OCI), a VCN (Virtual Cloud Network) is the foundational networking component that allows you to securely connect and isolate cloud resources like compute instances, databases, and load balancers.

What is a VCN in OCI?

A VCN (Virtual Cloud Network) is a software-defined private network that closely resembles a traditional on-premises network, including subnets, route tables, gateways, and firewall rules. It is region-specific and highly configurable.

Example Architecture:

OCI’s Virtual Cloud Network (VCN) allows you to build isolated, secure, and highly configurable networks in the cloud. Below are the key constructs used in OCI VCNs:

---

1. VCN (Virtual Cloud Network)

• A customizable, private network in a specific OCI region.

• CIDR block range: /16 to /30, e.g., 10.0.0.0/16.

• Supports multiple subnets and regional architecture.

---

2. Subnets

• Regional (not tied to availability domains).

• Two types:

  • Public Subnet: Associated with Internet Gateway; resources can be publicly accessible.

  • Private Subnet: No internet access; used for internal workloads.

---

3. Route Tables

• Define how traffic is routed from the subnet.

• Each subnet is associated with a single route table.

• Common targets:

  • Internet Gateway for public access

  • NAT Gateway for outbound access from private subnets

  • Service Gateway for OCI services (e.g., Object Storage)

  • Dynamic Routing Gateway (DRG) for on-premises or remote VCN connectivity

---

4. Internet Gateway (IG)

• Enables outbound and inbound internet traffic for public subnets.

• Must be added to the route table for use.

---

5. NAT Gateway

• Allows private subnet instances to access the internet for outbound-only communication.

• Keeps the resources not directly reachable from the internet.

---

6. Service Gateway

• Allows private subnets to access OCI services (like Object Storage) without using the internet.

• Traffic stays within the OCI network backbone.

---

7. Dynamic Routing Gateway (DRG)

• Connects a VCN with:

  • On-premises network over IPSec VPN

  • FastConnect (dedicated private connection)

  • Other VCNs (remote peering)

• Essential for hybrid and multi-region cloud setups.

---

8. Local and Remote Peering

• Local Peering: Connects two VCNs within the same region.

• Remote Peering: Connects VCNs across regions via DRG and RPC (Remote Peering Connection).

---

9. Security Lists

• Stateless or stateful firewall rules applied at the subnet level.

• Specify source/destination CIDRs, protocols, and ports.

• Less granular than NSGs.

---

10. Network Security Groups (NSGs)

• Apply firewall rules to individual resources (like compute instances or load balancers).

• Allow resource-level access control.

• Preferred over security lists for more precise configurations.

---

11. Public IPs

• Two types:

  • Ephemeral: Temporary, attached at instance launch.

  • Reserved: Static and can be attached/detached from resources.

---

Example: Simple OCI VCN Setup

Components:

• VCN: 10.0.0.0/16

• Public Subnet: 10.0.0.0/24 with IGW

• Private Subnet: 10.0.1.0/24 with NAT Gateway

• Internet Gateway

• NAT Gateway

• Route Tables (2): One for public, one for private subnet

• Security Lists or NSGs to control access

• Service Gateway for private access to OCI services

---
