Onboardbase

Onboardbase is the a secret management infrastructure platform that provides single source of shared truth for app secrets and usage. It helps dev teams securely share and work with environment-specific configs at every development stage, synced across infrastructure without compromising security - this means development teams can focus on building great apps rather than managing secrets and data. Secrets are dynamically kept up to date across your environments and infrastructure, with 50+ integrations and growing. Dev teams can monitor and audit how long, where and when your secrets are used and revoke usage anywhere with a click. Powerful always-on codebase scanning features prevent developers from accidentally leaking secrets to production, maintaining a robust security model.

OPNsense

Simple packet filters are becoming a thing of the past. Even the open-source domain is moving towards Next-Generation Firewalls. And OPNsense is a top player when it comes to intrusion detection, application control, web filtering, and anti-virus. No network is too insignificant to be spared by an attacker. Even home networks, washing machines, and smartwatches are threatened and require a secure environment. Firewalls are a component of the security concept. They protect against known and new threats to computers and networks. A firewall offers the highest level of protection if its functions are known, its operation is simple, and it is ideally positioned in the surrounding infrastructure. OPNsense accepts the challenge and meets these criteria in different ways. This book is the ideal companion for understanding, installing and setting up an OPNsense firewall.

Hybrid AD Manager

TideReach Ltd

Hybrid AD Manager puts the Active Directory consoles in a browser tab. Users and Computers, Sites and Services, Domains and Trusts, DNS and Group Policy each get their own tab, laid out like the Microsoft snap-ins, with your Entra ID tenant merged in: every account shows as synced, cloud-only or on-premises. RSAT is Windows-only, so admins on macOS, Linux or iPad normally need a Windows VM, a jump box or RDP. Here one MSI installs on a Windows server and everyone else opens a URL. 1.1 added 19 reports on accounts, passwords, computers, privileged access and security posture, each with a chart and CSV/PDF export. 1.2 adds Leavers: offboard someone across AD and Entra ID in one action - disable, reset password, revoke cloud sessions, strip groups, move the account - and undo it from the record. Admins sign in with their own AD accounts, so changes use their own rights and are audited. No agents, no database, no telemetry. Free edition and 30-day trial; Standard from $365/year.
