    EncryptPro Reviews

    EncryptPro

    PYTHONSOFTWARES (SMC-PRIVATE) LIMITED.

    $4
    Right-click a file to encrypt it for yourself, or for someone you're sharing it with — same menu, same two clicks. Shared files carry no password, no key management, and no email addresses — so the channel you share it over doesn't matter. Windows encryption with no containers, vaults, or drives to mount. Encrypt any file type. Double-click to open and edit it in its native application — changes save straight back to encrypted. Streaming decryption means a 10GB video plays within seconds while the rest decrypts in the background — no extract, no wait, no re-compress. Files stay where they are. Originals are overwritten with zeros, then random data, across multiple passes before deletion — unrecoverable even to forensic tools. Security groups organize encrypted files under separate passwords, so you unlock only what you're working on. Explorer icons show group and lock state at a glance, even when EncryptPro isn't running. Sharing runs on PGP-style key pairs generated once per connection. Keys never travel with the file — email it, put it on a public link, it makes no difference. C2 connections give teams one encrypt operation and universal member access, with no per-recipient steps. Only the creator needs a paid plan, so an entire team runs on one subscription. Keys derive from a master password we never receive, so your data is unreadable to us. There is no password recovery — any vendor offering account recovery necessarily holds something recoverable. We hold nothing readable. You can't be locked out of your data. Viewer Only Mode authenticates offline against your device. Expired subscription, no internet, our servers down, the company gone — your encrypted files still open. Windows only. Free version permanent, no credit card. Paid from $4/month.

    ShareWatcher Reviews

    ShareWatcher

    CodeLine

    $129 one-off (Pro)
    ShareWatcher is a Windows tool for anyone who needs to know what is happening on a file share: who is accessing it, and which files were added, changed or deleted, and when. Alerts arrive by email, as a sound, as a Windows event-log entry or by running a command you choose. Folders can be watched live, so a change is reported the instant it happens, or polled on a schedule, which also covers FTP servers and picks up files that arrived while the program was not running. Cadence Watcher raises the opposite alarm: a folder that should be receiving files has stopped. Actions handle new files as they land, including a QuickMove action that moves each one to the right folder by rule. The Server licence adds Auditing, recording who created, changed or deleted a file, and runs as a Windows service; Enterprise adds remote monitoring of other computers. Pro US$129, Server US$349, Enterprise US$749, paid once. Free 7-day trial. Windows 7 SP1 to 11 and Windows Server 2012 R2 and above.

    CVETodo

    $14.99
    Most CVE trackers stop at the raw record: description, CVSS score, done. CVETodo adds the layer that tells you what to actually do about it. Every vulnerability carries a 0-100 remediation priority score combining CVSS, EPSS likelihood, exploit availability and CISA KEV status, alongside a CISA SSVC decision path and MITRE ATT&CK technique mapping. An inventory agent, appliance registry and repository lockfile scanning match CVEs against what you genuinely run, cutting the noise of alerts for products you do not actually use. Browsing the full CVE database, priority scores and technical write-ups is free, no signup required. Paid tiers unlock real-time alerts, team workflows, remediation reporting, and an MSP tier for managing multiple client environments from one account.

    CacheGuard-OS is an open-source Linux-based UTM gateway appliance OS that has been in active development since 2002. It is designed to run on commodity x86 hardware and act as the default route between an internal network and the internet, replacing the ISP-provided router as the traffic checkpoint. The stack integrates: Squid (web cache and proxy), ClamAV (web antivirus), ModSecurity (WAF), StrongSwan (IPsec/IKEv2 VPN), IPRoute2 (QoS and WAN load balancing), NetFilter (stateful firewall), SSL inspection, and URL filtering. All components are configured through a web-based admin interface rather than directly, making the platform accessible to operators without deep Linux expertise while remaining auditable by those who want to inspect the underlying configuration. The OS has been open-source since its first release — source ships on every installed appliance. It was recently published publicly on GitHub to make the codebase easier to browse and audit. Target deployments are small to medium networks — SMBs, schools, and branch offices — where a commercial UTM appliance is overkill on budget but the threat surface is the same. Runs on bare metal or common hypervisors (VMware, VirtualBox, KVM, Hyper-V). No vendor lock-in, no subscription, no licence cost. GitHub: cacheguard/CacheGuard-OS

    Multilogin is a cloud phone platform built for social media marketers, agencies, and e-commerce sellers who manage multiple accounts at scale. It brings together what normally requires separate emulators, browser tools, and proxy services into a single dashboard, giving each account its own isolated space to run in. Apps like TikTok, Facebook, and Instagram operate on genuine Android cloud phone rather than simulated devices, so cached data, saved sessions, and login history carry over between uses, letting profiles develop naturally over time. Browser-dependent services such as Google Ads and Amazon instead run through separate sandboxed profiles, still handled from that same central hub. Residential and mobile-grade proxies with automatic location matching are included on every plan, so there's no separate sourcing needed. Teams can distribute devices and profiles using permission-based controls, scaling easily from a handful of accounts to hundreds.
