The added value of it is that every migration to a new version is initiated by the Cisco version itself, so that is a bunch of work that you don't have to do on the Cisco ESA system on-premise. As it becomes a safe platform, you don't need to invest anything in your own data center or in your upgrade path.
It's detection of true positives are great, as it's cloud based it's very scalable and stable.
A one-stop shop for email protection
The integration with FortiSandbox is good, and something that we utilize often.
Fortinet FortiMail is easy to use and the detection rate is very good. You can customize content filters and profiles are done easily. Additionally, there is a sandbox integration feature that is good.
The spam filtering, in particular, is very important for us. We have a large volume of emails each month, something like 200,000, and Barracuda filters about 85 percent of the spam, malware, and phishing that comes in. It prevents our users from receiving this content on their computers.
The basic features are okay and I'm satisfied with the Defender.
The solution is very easy to use. All you have to do is to assign the license to the end-user and it's done. The customer will only have the feature activated, and the solution will monitor the emails to determine if they are a threat or not.
Mimecast certainly helped my customers reduce phishing emails.
It's good, it keeps the spam out.
The solution is stable and the performance is good.
Symantec Messaging Gateway is stable and scalable. Installation is easy, and the deployment and maintenance can be done by one administrative person.
It has modules to detect malware and that is a strong point. It has a very nice way of showing you, directly in the product, a lot of details about certain pieces of malware. It goes very deep and even shows you the assembly code. It also does detonations on files and shows you the results in different operating systems. That is very useful.
What are the Different Types of Email Security?
Spam Filters - Marketing emails pour into most inboxes, at best clogging them with unneeded messages and at worst providing malicious links or phishing for sensitive information. Installing a spam filter can help by directing these spam emails into a separate email box so that your main inbox does not get clogged. You can also schedule them to be deleted automatically at fixed intervals.
Antivirus Protection - Even if spam emails are filtered into a separate mailbox, you might still open them and your computer and data might be compromised. Antivirus software scans your emails for malicious content and blocks them from entering or exiting your mailbox, as necessary. As opposed to a spam filter, which just redirects the messages, antivirus protection actually finds and eliminates malicious content.
Image and Content Control - Cyber attackers can include malicious software through files and links as well as images in their phishing emails.Therefore, all of these attachments must be scanned in order to protect your computer from hackers.
Data Encryption - Email data is generally transmitted in an open format and is therefore vulnerable while in transit. Your emails, including recipients’ details and message headers, should all be encrypted so that cyber attackers cannot see the contents or details of your emails. Data encryption is one of the best ways to avoid becoming a victim of phishing scams.
What are Email Attacks?
Email is the number one tool for business communication. As flexible, reliable, and convenient as it is, it is here to stay. But despite its benefits, email can be a vector for cyberattacks that can lead to data breaches and potentially billions of dollars in losses for businesses around the world. As digital technologies progress, cyber attackers continue to find new ways to exploit vulnerabilities in email accounts.
What are the Major Ways of Stealing Email Information?
Phishing is a kind of attack in which malicious emails designed to trick readers into falling for a scam are sent. Phishing campaigns generally try to get people to reveal credentials, financial information, or other sensitive data.
Spear Phishing is a targeted kind of phishing in which attackers send emails that appear to be from a trusted sender in order to obtain sensitive data. Spear phishing, which involves researching the victims and utilizing advanced intelligence strategies and social engineering techniques, is generally more successful than conventional phishing. Fewer messages are sent out, but they are more convincing.
Whaling is a form of phishing designed to target “whales” - high-profile executives - and manipulate them into authorizing high-value wire transfers to the cyber attacker. Instead of trying to get users to click on links in order to infect their computers with malware, whaling uses email and website spoofing and social engineering to trick users into disclosing sensitive information.
In a business email compromise (BEC) attack, a threat actor accesses a corporate email account and sends fraudulent emails from it in order to steal money from the company’s customers, employees, or partners.
Malware refers to malicious software designed to damage, disrupt, or gain unauthorized access to a computer system. Malware can encrypt or delete sensitive data, steal, hijack, or alter central computing functions, and monitor users’ activity without their knowledge or permission.
Ransomware is a kind of malware that blocks access to the computer system until a ransom is paid. It encrypts the victim’s files until the demanded payment has been made.
Unsolicited spam email - Aside from being annoying, spam may also contain malicious attachments or links and can also be a vector for other kinds of attacks, such as phishing and malware.
Computer viruses are a type of malware that replicate and spread by modifying other computer programs and inserting their own code. Computer viruses can harm hardware, destroy data, compromise sensitive information, and waste time, resources, and energy. Most computer viruses are email viruses, which are activated when a user interacts with the infected email by clicking on a link or downloading an attachment.
In zero-day attacks, a threat actor exploits a vulnerability before the developers have had a chance to release a fix for it. These attacks can result in data theft, lost productivity, system downtime, damaged company reputations, and regulatory actions.
What is Phishing?
Phishing is a cybercrime in which targets are contacted by email (or by telephone or text message) by a hacker who is posing as a legitimate institution in order to lure the victim into divulging sensitive data such as passwords or other credentials or banking or credit card details.
The information is then used to access accounts and steal identities and/or money.
Phishing is a cheap, easy, and effective means of cyber attack and is therefore the most prevalent type of cybercrime. 75% of organizations worldwide experienced a phishing attack in the year 2020.
“Phishing” can also be used as an umbrella term referring to any type of social engineering attack that takes place over email.
Common features of phishing emails include:
- Attention-grabbing statements that seem too good to be true
- A sense of urgency (e.g. limited-time offers or a threat that your account will be terminated unless you update your personal details immediately)
- A hyperlink that is not what it appears to be or looks like a popular website but is slightly misspelled
- An attachment that might contain viruses or ransomware
- Something that seems off, out of character, or suspicious. Trust your instincts!
How Do You Stop Email Threats?
Here are some ways you can reduce the risk of email-based cyber attacks:
- Protect your emails with end-to-end encryption to protect them against data leaks so that third parties can’t read them.
- Use a spam filter, which will assess the origin of the message, the software used to send it, and the message’s appearance to determine if it is spam. Be aware that these filters are not 100% accurate and may sometimes block emails from legitimate sources.
- Restrict administrator privileges.
- Restrict the downloading of files from suspicious sources by changing your browser settings to block access to such sources.
- Ensure that systems are secured with hard-to-guess passwords that are changed regularly. Never use the same password for more than one account.
- If a website asks you for verification, check with the company personally before you enter any details online. The request may be legitimate but it may be a scam.
- Before clicking on a link in an email, hover over the URL. A secure website with a valid Secure Socket Layer (SSL) certificate will begin with “https”.
- Most banks and financial institutions will provide your account number or other personal details in their emails to let you know that they are being sent from a reliable source. Be wary of any emails that threaten to suspend your account if you do not update your personal details.
- Educate your employees on how not to become prey to email threats.
What Percentage of Attacks Come Through Email?
90% of all cyber attacks come from email. Although 78% of people know not to click on a suspicious email, 4% of people who receive any given phishing email will click on it. This might not sound like a lot, but it means that for every 25 people you employ, one of them is likely to be scammed.
How to Tell if Your Email Account Has Been Hacked
Here are five signs that indicate your email account might have been compromised:
1. Your password has been changed - If you didn’t change your password but it is being rejected as incorrect, someone may have altered it.
2. Emails (either outgoing or incoming) that you don’t recognise - If you see emails in your sent mail folder that you don’t remember sending, a hacker may have access to your email account. You may also notice that you are receiving password reset emails from websites where hackers are trying to change your password.
3. Unexpected emails - If hackers have gained access to your email account, they may incorporate personal information they have found in your emails into messages they have penned from your bank or credit card company. If you receive a message like this and are unsure whether it is legitimate, call your bank to verify that they are really trying to get in touch with you.
4.Unfamiliar IP addresses show up on your log - If your email shows that you have logged in from an unfamiliar IP address, this is a sign that someone is accessing your account from another location.
5. Your contacts are receiving spam messages from you - If your friends are receiving spam from your email address, you may have been hacked and your personal data is at risk.
