    What our customers say:

    I just started using the service of Quttera and can say I am amazingly pleased with the results. I had 2 different websites that were thoroughly infected with malware. I tried testing for malware on other sites and none of them registered a problem. Only Google and Quttera could recognize the issue at hand. What happened next was an introduction to fair pricing along with excellent customer service team who cleaned my sites within a 24 hour period. Then they actually took it upon themselves to get one of the sites off Google's blacklist. I am up and running while at the same time being monitored to prevent future issues. Very cool.

    Anthony Campagna, Jump On It, Inc.

    I am extremely happy with your prompt and professional service. My client was on Google's blacklist for four months even though the malicious code on her small business site was removed immediately after the incident. We tried and tried to contact Google and were ignored. Your team responded promptly and had everything back up and running within a matter of days.

    Found malware on my site, janeco.ca, downloaded the Quttera plugin which gave me a breakdown of affected pages. Simply asked for the team at Quttera to look into it, they then proceeded to remove ALL Malware within a few hours of initial notification! All I can say is a BIG THANK YOU!

    Why is it critical for small and medium-sized businesses to adopt strategies for fighting cyberthreats?

    Website Protection & Hacking Remediation | Quttera Website Security

    Small and medium businesses use ThreatSign as their cybersecurity platform to protect business-critical digital assets and data. Website owners can concentrate on the ultimate goal - take the business to the next level. While ThreatSign takes care of securing this journey, protecting them from cybercriminals and malware.

    Cybersecurity is a major issue for the small and medium-sized businesses sector:

    • More than 1 mil new malware samples detected per day
    • A typical business website is attacked more than 40 times per day
    • Roughly 50% of all small businesses in the US have been attacked by hackers at some point in time

    With ThreatSign you can automatically block attacks, detect threats that are new and missed by traditional anti-virus solutions, remove malware & blacklist, harden the CMS files, detect DNS attacks, and much more.

    Why do your customers care about website security?

    Your online reputation is critical to business growth and your branding image. A secured and protected website is crucial when gaining the trust of a prospect. It is essential for a potential customer to be confident that you will handle their information securely before making a purchase or even sign up for a free service.

    When Google blacklists your website, or Yahoo, or even when desktop anti-virus program blocks your site a potential customer will see a warning page when trying to visit your website. New Ipsos study of 20K+ internet users in 24 countries shows - 51% of the global internet users choose to not buy online because of the security and privacy concerns. (Source: 2017 CIGI-Ipsos Global Survey on Internet Security and Trust | Internet Governance & Jurisdiction ).

    Managing and mitigating your security risks benefits both you and your customers. Having proper anti-malware services in place provides one of the best Return On Investment (ROI) of spending on IT security for a business of any size.

    How does malware cleanup work?

    A dedicated cyber-security professional is assigned to every customer, and he will lead the website malware removal process. The malware removal process is conducted remotely using FTP/HTTP/SFTP and via SSH. Malware cleanup is not completed without blacklisting removal. Hence once the site is clean we submit it for blacklist removal(reconsideration request) to all relevant authorities.

    To initiate the malware removal from your website, login into your THREATSIGN! user dashboard UI and fill in the Malware Removal Request form. Once submitted, the support ticket will be automatically created and one of our malware analysts will be assigned to it.

    Does Quttera work with my hosting provider?

    Yes, we do. We support and work with any hosting provider in the world (including virtual hosting providers such as a managed host).
