Non-Approved Messaging Apps create backchannels that bypass controls, audit trails and record retention. You should deploy an approved messaging tool, enforce mobile device management and use data loss prevention. Train staff and run audits to reduce leaks and speed incident response.
Use Proxmox Notes HTML Comments to hide short-term secrets from the rendered Notes panel. You will still see them in the editor and configuration. Treat comments as a convenience; rotate or move your secrets to a vault.
Troubleshoot Lets Encrypt certificate failures on a Sophos firewall. You confirm DNS A records, port 80 reachability and that the ACME HTTP-01 token URL returns HTTP 200. Use dig and curl to test the exact token path. Fix NAT, firewall rules or proxies that block or rewrite /.well-known/acme-challenge.
Remove Sophos Tamper Protection offline using Safe Mode when your device cannot check in. You get clear checks, commands and remediation steps. Reboot to Safe Mode, stop Sophos services, remove files and clean registry keys, then reboot and verify no Sophos services remain.
Peer Administration on a Sophos XGS HA cluster only behaves if the network layout is thought through first. Keep client traffic, the HA heartbeat and management on separate paths where you can. A dedicated HA link is the cleanest option. I would use a small heartbeat subnet, such as 172.16.100.0/30 between the primary and auxiliary. […]

For Exchange Server security, reduce your exposed services. Remove unused roles, lock down IIS, disable legacy protocols and isolate admin accounts. Use dedicated admin workstations, enforce MFA, keep TLS current and apply patches promptly.
AI web browsers security is an urgent concern for your data. This article explains risks such as prompt injection, data exposure and agent autonomy. You get concrete examples and immediate steps to reduce exposure, isolate agents and limit permissions.
SSL VPN Dual Stack can let IPv6 bypass the tunnel and break IP based controls. This guide shows how you can force IPv4, use split DNS, or add IPv6 egress so your remote clients present the office IP and your security checks remain consistent.
AI scraping prevention starts with layered defences you can apply to your site now. Use IP blocking, strict firewall rules, rate limits and tighter privacy settings to stop mass harvesting. Log incidents for enforcement, escalate blocks by behaviour, and require authenticated access for bulk data to deter and document scraping attempts.
Threat landscape Overview of AI sidebar extensions AI sidebar extensions run code inside the browser and call external AI APIs. They often ask for broad permissions, such as host access to all sites, cross-origin requests, or native messaging to local processes. That access lets an extension read page content, intercept form data, or inject scripts...
I tried Atlas so I could see the security trade-offs first hand. The browser agent that automates browsing is useful, and it also widens the attack surface. That makes Atlas browser security a practical issue rather than an abstract one. The steps below stick to controls that can be applied now. I have kept the […]
Phishing emails aimed at LastPass users are trying to steal your master password. The fix is boring, but it works: check the message properly, harden the account, and do not trust anything that asks for secrets by email. Recognising Phishing Threats Common phishing methods Credential harvesting pages. An attacker sends an email with a link [&hellip...
I hit this twice on different Sophos firewalls. I imported a signed SSL certificate, went to assign it to SSL VPN, and the dropdown still only showed ApplianceCertificate. The firewall kept presenting the old certificate. These are the checks that mattered. What you see The SSL Certificate Selection menu in the VPN settings will not […]

Enhance your homelab security with a data-driven Cyber Risk Management Framework. Learn to efficiently assess risks, automate responses, and fortify your network.
Getting started with ambient AI security Ambient AI means systems that run in the background and act without a direct prompt. In a home lab that usually means voice assistants, local cameras with pattern detection, presence sensors and automation that infers intent. The security issue is persistent sensing. That changes how I think about access,...
Discover how to enhance your Sophos XG 310 Home Edition with a Flexi Port Module for added SFP+ connectivity. Navigate setup challenges and maximize performance.
Patching container images with HarborGuard automation I use HarborGuard to cut the time between finding a vulnerability and shipping a patched image. It sits in the path between scanning, rebuilds and promotion, which means the boring part can be handled by the pipeline instead of me staring at a report and muttering at it. Introduction […]
Automating Your Home with AI: A Practical Blueprint for Local Control I keep home automation local where I can. It gives me predictable latency, better privacy control and fewer cloudy failure modes. This comes down to local AI home automation, sensible network layout and firewall rules that do not get clever for the sake of […]
