I have a constant problem with my website. Once in several weeks it gets hacked and spreads malware.
Recently I hired a guy who said he fixed all the vulnerabilities. But I want to be sure that my website is not going to be hacked again. Can you recommend some services/companies that can evaluate security of my website. Since it is a private project, I cannot afford expensive solution.
Will be grateful for any advice.

You can try tools like Metasploit or Cain & Abel which are free tools and paid tools like Nessus.
If you are planning to do a penetration test, you may read this blog. It must be helpful for you

1. Stay updated.|
You need to stay up to date with hacking threats. If you have at least a basic knowledge of what is possible then you can protect your website against it. Follow updates at a tech site such as The Hacker News. Use the information you gain to put fresh precautions in place when necessary.
2. Toughen up access control.
The admin level of your website is an easy way into everything you do not want a hacker to see. Enforce user names and passwords that cannot be guessed. Change the default database prefix from “wp6_” to something random and harder to guess. Limit the number of login attempts within a certain time, even with password resets, because email accounts can be hacked as well. Never send login details by email, in case an unauthorized user has gained access to the account.
3. Update everything.
Updates cost software companies money. They only do it when necessary, yet many people who use the software do not install updates immediately. If the reason behind the update is security vulnerability, delaying an update exposes you to attack in the interim period. Hackers can scan thousands of websites an hour looking for vulnerabilities that will allow them to break in. They network like crazy, so if one hacker knows how to get into a program then hundreds of hackers will know as well.
4. Tighten network security.
Computer users in your office may be inadvertently providing an easy access route to your website servers. Ensure that:
• Logins expire after a short period of inactivity.
• Passwords are changed frequently.
• Passwords are strong and NEVER written down.
• All devices plugged into the network are scanned for malware each time they are attached.
5. Install a web application firewall.
A web application firewall (WAF) can be software or hardware based. It sets between your website server and the data connection and reads every bit of data passing through it.
Most of the modern WAFs are cloud based and provided as a plug-and-play service, for a modest monthly subscription fee. Basically, the cloud service is deployed in front of your server, where it serves as a gateway for all incoming traffic. Once installed, web application firewall provides complete peace of mind, by blocking all hacking attempts and also filtering out other types of unwanted traffic, like spammers and malicious bots.
6. Install security applications.
While not as effective as a full blown WAF, there are some free and paid for security applications that you can install that will make life a bit more difficult for hackers. In fact, even some free plugins such as that fromAcunetix WP Security can provide an additional level of protection by hiding the identity of your website’s CMS. By doing so this tool makes you more resilient against automated hacking tools that scout the web, looking for WordPress sites with specific build and version, which has one or more known vulnerabilities.
7. Hide admin pages.
You do not want your admin pages to be indexed by search engines, so you should use the robots_txt file to discourage search engines from listing them. If they are not indexed then they are harder for hackers to find.
8. Limit file uploads.
File uploads are a major concern. No matter how thoroughly the system checks them out, bugs can still get through and allow a hacker unlimited access to your site’s data. The best solution is to prevent direct access to any uploaded files. Store them outside the root directory and use a script to access them when necessary. Your web host will probably help you to set this up.
9. Use SSL.
Use an encrypted SSL protocol to transfer users’ personal information between the website and your database. This will prevent the information being read in transit and accesses without the proper authority.
10. Remove form auto-fill.
When you leave auto-fill enabled for forms on your website, you leave it vulnerable to attack from any user’s computer or phone that has been stolen. You should never expose your website to attacks that utilize the laziness of a legitimate user.
11. Back-up frequently.
Just in case the worst happens anyway, keep everything backed-up. Back up on-site, back up off-site, back up everything multiple times a day. Every time a user saves a file it should automatically back up in multiple locations. Backing up once a day means that you lose that day’s data when your hard drive fails. Remember every hard drive willfail.
12. You can't hide your code.
You can buy software that says it will hide the code on your webpages. It doesn’t work. Browsers need access to your code in order to render your website pages, so there are simple ways to get around web-page “encryption.”
Disabling “right-click” as a way to view your website code is annoying to users because it also disables every other “right-click” function, and there are simple workarounds that every hacker knows anyway. If you have been told that it is possible then read this article
