Cybercrime is one of the world’s fastest-growing threats, with malicious actors constantly elaborating their methods of undetectable intrusion. According to Verizon’s Business 2020 Data Breach Investigations report, there has been a 100% increase in web app breaches, and stolen credentials were used in more than 80% of these cases. These statistics are worrying for many businesses that actively move their processes to the cloud and deal heavily with customers’ personal data.
Under these circumstances, companies need to run regular automated and manual tests to determine weak spots in their infrastructure, software, network and physical perimeter security. One of the most efficient testing methods is security penetration testing, or pentesting.
Pentesting is a benign hacking attempt, manual or automated, to break into the system and uncover its vulnerabilities before actual cyber criminals do it. This method is directed at testing the system security controls for their real-world effectiveness. It involves such stages as data collection, threat modeling, vulnerability scans, penetration tests, and so on.
To get proactive with their cyber security protection, many businesses cooperate with professional security testing companies that are able to comprehensively check the system, identify risks, fix vulnerabilities, and stay one step ahead of potential hackers.
When asking a professional software testing company to check your system’s security, in most cases you need to grant them access to sensitive information. For this reason, it’s important to choose a reliable company with an exceptional reputation, which will become your trusted partner.
Unsurprisingly, the market of security penetration testing companies is overwhelmingly crowded. To narrow down your search, we have analyzed hundreds of testing companies and compiled the list of top testing professionals. We have applied the following criteria:
As a result, we’ve picked 30 skilled security testing companies and rated them accordingly.

MySQL does not limit the number of slaves that you can connect to the master server in a replication topology. However, as the number of slaves increases, they will have a toll on the master resources because the binary logs will need to be served to different slaves working at different speeds. If the data churn on the master is high, the serving of binary logs alone could saturate the network interface of the master.
A classic solution for this problem is to deploy a binlog server – an intermediate proxy server that sits between the master and its slaves. The binlog server is set up as a slave to the master, and in turn, acts as a master to the original set of slaves. It receives binary log events from the master, does not apply these events, but serves them to all the other slaves. This way, the load on the master is tremendously reduced, and at the same time, the binlog server serves the binlogs more efficiently to slaves since it does not have to do any other database server processing.
Ripple is an open source binlog server developed by Pavel Ivanov. A blog post from Percona, titled MySQL Ripple: The First Impression of a MySQL Binlog Server, gives a very good introduction to deploying and using Ripple. I had an opportunity to explore Ripple in some more detail and wanted to share my observations through this post.
Ripple supports only GTID mode, and not file and position-based replication. If your master is running in non-GTID mode, you will get this error from Ripple:
Failed to read packet: Got error reading packet from server: The replication sender thread cannot start in AUTO_POSITION mode: this server has GTID_MODE = OFF instead of ON.
You can specify Server_id and UUID for the ripple server using the cmd line options: -ripple_server_id and -ripple_server_uuid
Both are optional parameters, and if not specified, Ripple will use the default server_id=112211 and uuid will be auto generated.
While connecting to the master, you can specify the replication user and password using the command line options:
-ripple_master_user and -ripple_master_password
You can use the command line options -ripple_server_ports and -ripple_server_address to specify the connection end points for the Ripple server. Ensure to specify the network accessible hostname or IP address of your Ripple server as the -rippple_server_address. Otherwise, by default, Ripple will bind to localhost and hence you will not be able to connect to it remotely.
You can use the CHANGE MASTER TO command to connect your slaves to replicate from the Ripple server.
To ensure that Ripple can authenticate the password that you use to connect to it, you need to start Ripple by specifying the option -ripple_server_password_hash
For example, if you start the ripple server with the command:
rippled -ripple_datadir=./binlog_server -ripple_master_address= <master ip> -ripple_master_port=3306 -ripple_master_user=repl -ripple_master_password='password' -ripple_server_ports=15000 -ripple_server_address='172.31.23.201' -ripple_server_password_hash='EF8C75CB6E99A0732D2DE207DAEF65D555BDFB8E'
you can use the following CHANGE MASTER TO command to connect from the slave:
CHANGE MASTER TO master_host='172.31.23.201', master_port=15000, master_password=’XpKWeZRNH5#satCI’, master_user=’rep’
Note that the password hash specified for the Ripple server corresponds to the text password used in the CHANGE MASTER TO command. Currently, Ripple does not authenticate based on the usernames and accepts any non-empty username as long as the password matches.
It’s possible to monitor and manage the Ripple server using the MySQL protocol from any standard MySQL client. There are a limited set of commands that are supported which you can see directly in the source code on the mysql-ripple GitHub page.
Some of the useful commands are:
SELECT @@global.gtid_executed;– To see the GTID SET of the Ripple server based on its downloaded binary logs.
STOP SLAVE;– To disconnect the Ripple server from the master.
START SLAVE;– To connect the Ripple server to the master.
