Linux Server Security and PBX Protection
Monitor and Manage Security Across Linux Servers and PBX Systems
PBX.Management monitors suspicious SIP activity, SSH authentication failures, web threats and port-scanning activity across supported Linux servers. Review potential threats and manage firewall rules across one server or an entire fleet without logging into every machine.
Simple pricing at $1 per server per day. Built for Asterisk, FreePBX, VitalPBX and supported Linux servers.
Internet-Facing Linux Servers and PBX Systems Face Constant Security Threats
Any Linux server exposed to the internet can be targeted by automated scanners, SSH brute-force attacks, web probes and attempts to exploit open services. PBX systems face the additional risk of SIP credential attacks, fraudulent calls, service disruption and unexpected carrier charges.
PBX.Management brings detected activity into one central dashboard so operators can review potential threats and apply controlled firewall rules across their servers.
SIP Attacks and Toll Fraud
Identify suspicious REGISTER attempts, INVITE activity and repeated authentication failures so they can be reviewed and actioned earlier.
SSH Brute-Force Attacks
See repeated SSH login failures and review source addresses that may be attempting unauthorised access.
Port Scanning and Web Probes
Surface activity consistent with port scanning, web probing and attempts to access exposed internet services.
Manual Firewall Management
Stop logging into every server separately to edit nftables or iptables rules by hand.
No Central Visibility
Bring server threats, firewall activity and protection status into one dashboard.
Inconsistent Server Protection
Apply clear and consistent firewall policies across one server or an entire managed fleet.
One Dashboard for Linux Server Security and PBX Firewall Management
A lightweight agent runs on each supported Linux server and reports security activity to the PBX.Management platform using outbound HTTPS.
Operators can review SIP, SSH, web and port-scan events, create block or allow rules, apply country-based restrictions and manage firewall policies across multiple servers from one central console.
PBX.Management is purpose-built for PBX and SIP infrastructure while also providing threat visibility and firewall management for other supported Linux servers.
- Monitor SIP, SSH, web and port-scanning activity in real time
- Review suspicious sources and apply block or allow rules from one place
- Keep policy consistent across a single server or an entire fleet

Rapid Agent Onboarding
Connect a supported Linux server using a guided installation command and begin receiving activity shortly after registration.
nftables and iptables Support
Apply managed firewall rules through the Linux firewall backend already supported by the server.
Secure Data Handling
Collect only the metadata needed for threat monitoring and firewall management. Do not collect call audio, SIP passwords or full packet captures.
Get Started in Five Steps
From account creation to applying firewall rules, onboarding a supported Linux server can generally be completed in minutes, depending on the server environment and configuration.
Create Your Account
Request access and create an organisation for your server environment.
Add a Server
Add a supported Linux server or PBX and generate its secure registration credentials.
Install the Agent
Run the guided installation command. The lightweight agent connects to the platform using outbound HTTPS.
Monitor Threat Activity
Review SIP, SSH, web and port-scanning activity in the central dashboard.
Apply Firewall Rules
Review detected sources, then choose whether to block, allow or ignore them and apply firewall policies to one server or across the account.
Example install command
curl -fsSL https://pbx.management/install.sh | sudo bashShared threat indicators with data minimisation
When different organisations block the same source address, that shared information may help other operators recognise potentially suspicious sources. PBX.Management uses organisation-de-identified threat indicators without sharing private notes or call content.
Shared intelligence focuses on attack patterns such as repeat offenders and scanning behaviour — not the content of your calls or your business data.
Organisation-de-identified by design
Indicators are focused on abusive network sources and behaviour, not on your calls or customers.
Faster recognition
Review source addresses that have also been blocked by other participating organisations.
Community driven
Participating servers contribute organisation-de-identified indicators that may provide a broader view of suspicious activity.
Built around data minimisation
PBX.Management focuses on the SIP signalling metadata and firewall state needed to keep your servers secure. It is not designed to record or store call audio. We collect what is necessary to do the job, and no more.

Important Security Information
PBX.Management is a monitoring and firewall management platform designed to help organisations identify suspicious activity and reduce security risk. It cannot detect or prevent every attack, compromise, fraud event, service interruption or configuration error. Customers remain responsible for maintaining their servers, PBX systems, software updates, credentials, backups, network configuration and carrier fraud controls. Firewall actions may block legitimate traffic if rules are created incorrectly, and all block, allow and country-based rules should be reviewed before use.

Frequently asked questions
What is PBX.Management?
PBX.Management is a platform for monitoring security threats and managing firewall rules on supported Linux servers, purpose-built for PBX and SIP environments. A lightweight agent on each server streams activity to a central console where you can review threats and apply block or allow rules.
Can PBX.Management protect a Linux server that is not a PBX?
Yes. On supported Linux distributions, PBX.Management can monitor SSH authentication failures, web threats and port-scanning activity and can manage firewall rules. SIP-specific monitoring only applies when a SIP service is running.
What threats does PBX.Management monitor?
The platform monitors SIP activity, SSH authentication failures, suspicious web activity and port-scanning behaviour reported by the installed agent.
Does PBX.Management automatically block every detected threat?
No. Operators review detected activity and decide whether to block, allow or ignore a source. Country blocks and existing managed firewall policies are enforced automatically after they are saved.
Does PBX.Management replace my existing firewall?
No. It manages its own dedicated nftables table or iptables chain and is designed not to overwrite unrelated firewall rules.
Which Linux systems are supported?
PBX.Management officially supports Ubuntu 20.04, 22.04 and 24.04, Debian 11 and 12, Rocky Linux 8 and 9, and AlmaLinux 8 and 9.
Does the platform collect call recordings or passwords?
No. It does not collect call audio, SIP passwords or full packet captures. It collects the security metadata required to identify threats and manage firewall decisions.
How much does it cost?
Pricing is $1 per server per day. You pay for the number of servers you connect, with no separate licence for the console itself.
Which PBX platforms are supported?
PBX.Management works with common SIP-based systems including Asterisk, FreePBX, VitalPBX, FreeSWITCH, Kamailio, OpenSIPS and custom SIP platforms running on supported Linux servers.
Does it work with nftables and iptables?
Yes. The agent supports common Linux firewall backends including nftables and iptables so rules apply the way your servers already expect.
How does the agent connect to my server?
You register a server in the console to generate secure credentials, then run a single guided install command. The agent connects outbound to the platform over HTTPS, so you do not need to expose new inbound management ports.
Can it block traffic by country?
Yes. You can restrict traffic by country using managed IPv4 and IPv6 network ranges, so your servers only accept traffic from the regions where your business operates.
Can I manage more than one server?
Yes. You can manage a single server or a large fleet from one console, with consistent policy and a shared view of activity across servers.
What is community threat intelligence?
Community threat intelligence, currently a Preview feature, uses organisation-de-identified threat indicators reported across participating organisations to help you recognise abusive sources faster. Shared data focuses on threat indicators, not the content of your calls.
Will this stop every attack?
No. No security product can detect or prevent every attack. PBX.Management provides threat visibility and central firewall management to help operators identify suspicious activity and reduce risk. It should be used alongside secure configuration, software updates, strong credentials, backups and appropriate carrier fraud controls.
Can firewall rules block legitimate traffic?
Yes. Blocking an incorrect IP address, network range or country may interrupt legitimate SIP trunks, remote users, administrators, monitoring systems or customer traffic. Operators are responsible for reviewing rules before applying them and for maintaining appropriate allow rules.
Is IP country information always accurate?
No. IP geolocation data is useful for country-based firewall management but is not guaranteed to be completely accurate or current. VPNs, proxies, hosting providers and recently reassigned network ranges may affect results.
How quickly can I get started?
Most servers can be connected in minutes. After you add a server and run the install command, activity begins streaming into your dashboard right away.
Do you offer role-based access for teams?
Yes. You can give team members the right level of access, from full administrators to read-only viewers, and every administrative action is recorded in the audit log.
Is it suitable for MSPs and providers?
Yes. Managed service providers and VoIP or SIP providers can monitor threats and manage firewall rules across multiple client servers with role-based access and clear audit trails.
