Cosmos Hosting
CEO

“Very light on resources, to the point its almost not there and suitable on even
the smallest of web-servers. Night and day compared to bitninja.”…”CPU/Memory
usage ironically went down due it blocking such a number of attacks (confirmed
in logs) and would likely pay for itself twice over in production”…”Apparently
there is allot of magic in the email scanning to block for malware and phishing
links”…”Certainly a very worthwhile and powerful tool to consider if you don’t
have any security solutions or firewalls in place.”

Media Serve
CEO

“I’ve switched 12 Enhance servers to cPFence from cPGuard”…”Support is
fanatical. Quick and efficient and provides a fast version release when issues
are encountered. (I have so much going on every single day so my typos are fast
& furious, and often incorrect but they’ve been extremely patient with
me!)”…”cPGuard isn’t really able to secure email only or database only Enhance
servers but cPFence can.”…”Three releases between Friday and Monday is
phenomenal.”…”cPGuard is awesome, but for Enhance cPFence is at the very least
equivalent and built for Enhance / OLS & LS.”

PDudeP
CEO

“I’m using cPFence on 7 of my main servers, for a few weeks now.I have to say
I’m very pleased with it. No problems at all.”…”On one email server I have
around 300GB of emails, and it continues to find emails “here and there” with
malware, and moving them to quarentine.”…”I have a personal (of mine) email
account that I use to register everywhere for non important things, and that
account receives lots of SPAM. For that account only, a few days ago, it
detected 2400 infected emails! WOW.”…”Regarding support, I have to say it really
is top-notch.
And I am NOT affiliated with cPFence in any sense. 🙂”

Ask A QuestionAsk A Question



Who is behind cPFence, and is it safe to use?

cPFence was created by our hosting and software development company, Linkers
Gate LLC. Our company is registered with Company Number: 105300800219093, VAT:
752-267-353, and Dun & Bradstreet under D-U-N-S Number 561227945. We are a small
team of six talented server admins and developers. We originally developed
cPFence for our own use, and it has served us exceptionally well, to the point
where we install it by default on all our clients’ servers. To protect the
software, we wrapped it in a license-based system, and we’ve recently decided to
offer it to the public in two versions: a free version (antivirus only) and a
paid version (full features).

Is it safe?
Yes, it’s very safe. Our software is written entirely in Bash scripting, then
obfuscated and converted to binary for code protection—nothing fancy or
complicated. No additional services or new users are installed on the server.
Unlike other software based on PHP, our solution is generally lighter on system
resources and can be easier to audit, especially for those familiar with Bash.
It’s straightforward for any skilled security researcher to monitor its actions
and ensure its security. Additionally, we don’t store any information or
maintain active connections between the host and our license servers. We’ve
designed it to be easy, simple, yet powerful.

Why Does cPFence Only Support Enhance Panel?

Because it was already developed and ready to use! cPFence was initially built
for our own use across all servers in our hosting and server management company.
Since we exclusively use the Enhance control panel and find it perfectly aligned
with our business model, cPFence was specifically designed to support it. We may
consider adding support for other control panels like cPanel, DirectAdmin, etc.,
in the future if there is sufficient demand.

Has cPFence been tested for the Mail Server, Database, and Main Control Panel
roles?

Yes, cPFence has been heavily tested on all Enhance server roles, including the
Main Control Panel and Email roles. It’s specifically designed to detect and
block malware and phishing links in incoming emails.

When will UI integration be available for cPFence in the Enhance control panel?

UI integration will be available as soon as the Enhance team completes the
necessary API.

How do the Owl and virus detection features work in cPFence?

cPFence Owl was initially developed to do the following:

1- Monitor CPU, RAM, and IO usage, and adjust the speed of running scanning
processes accordingly to keep system load under control. If high resource usage
is detected, the admin is notified based on their notification settings.

2- Periodically check for and search signs of common and recent webshells and
malware that have been active online in the last 30 days.

3- Terminate slow, long-running, or sleeping MySQL queries for blacklisted users
only.

4- Kill processes when an excessive number of processes is detected from an
abusive user.

5- Analyze logs to detect IPs involved in repeated DDoS attacks and apply a
temporary block to protect the system.

These are the most important functions. However, in the latest versions, we had
to temporarily disable feature number 4 after releasing the software to the
public due to some false positives in certain environments and scenarios. The
feature that terminates processes from abusive users is currently on hold until
we can conduct extensive tests and ensure it is 100% free of false positives for
everyone.

Regarding malware blocking, cPFence monitors changed, modified, or added files
and scans them using our extensive hourly updated malware signatures. If any
malware is found, it is quarantined, and a notification email is sent to the
admin.

Why are so many IPs blocked by cPFence Protection?

The IPs you’re seeing in the list are primarily from bots and scanners that are
constantly probing the internet for vulnerabilities, scanning ports, and
generally doing harmful activities. Unfortunately, the internet is filled with
these malicious IPs these days.

cPFence maintains a comprehensive IP database (IPDB) that includes known
spammers, scanners, and hacker IPs. We block these IPs at the network level
before they can even reach your server. This proactive protection helps keep
your server secure and reduces unnecessary resource usage.

You can monitor the logs for these actions in /var/log/syslog. To view the
cPFence blockages in real-time, you can use the following command:

sudo tail -f /var/log/syslog | grep -E 'cPFence Blocked:|cPFence DDos
Protection:'

If you’d like to see the difference, you can temporarily disable cPFence and
monitor the syslogs to observe how these bad bots and scanners could otherwise
consume your server’s resources.

How does cPFence WAF work compared to competitors?

Our WAF outperforms most so-called ‘commercial WAF’ services popular in the
shared hosting industry. But don’t just take our word for it—use this
third-party WAF testing tool to test and see for yourself.

We primarily use a combination of modified and tweaked OWASP and Comodo WAF
rules, along with custom rules built from scratch, to provide added security and
increased compatibility with shared hosting environments, minimizing false
positives as much as possible.

We override the LiteSpeed/OLS settings to ensure your rules are always synced
with our latest version. This allows us to issue immediate vulnerability
mitigations for all our clients’ servers in one shot, ensuring everyone stays
secure.

How do I install cPFence?

First you need to get your license. To install cPFence, open a terminal on your
server and enter the one-line installation code provided on your screen. This
code automatically detects your server’s capabilities and will install the
recommended protections for your server in less than 2 minutes.

Can I move my license to a new server?

Yes, you can easily move your cPFence license to a new server using the reissue
license feature found in clients area. This process is straightforward and
hassle-free.

Do you offer Bulk licenses ?

Yes, we offer bulk licenses for 10+ servers. Please order your bulk license
through this link. Ensure you provide the full list of your server IPs so we can
manually activate them under one license key. Bulk licenses do not have
automatic activation and will be activated asap upon receiving payment. Single
server licenses do have automatic activation.

How does your DDos protection work?

Our DDos protection module instantly blocks any IP with more than 100 concurrent
connections to the server. It is designed to block aggressive IPs that
repeatedly attempt attacks. Initially, the block is temporary, but if the same
IP triggers multiple attacks, it results in a permanent block, and our IPDB is
updated accordingly so all servers get the latest protection. You can adjust the
limit in the configuration file located at /opt/cpfence/config.conf. The default
value of 100 is recommended for optimal performance.
