How to Validate an Email Address for Typos, Syntax, Curse Words, and Other Rules

How to Validate an Email Address for Typos, Syntax, Curse Words, and Other Rules

Email marketing is without a doubt sound investment for companies. For every $1 spent on email marketing, the return on investment (ROI) can be as high as $32.28, according to DMA’s Marketer Email Tracker report.

The same study examined the respondents’ mailable list size, return rates, and delivery rates, and the findings are quite surprising. Some 55% of the respondents said there was a significant rise in their organization’s mailable list size, yet only 36% reported increased delivery rates. Also, 36% of the respondents said they encountered an increase in the number of returned emails.

Using Domain Ownership History to Secure Next-Gen Firewall Estates

Using Domain Ownership History to Secure Next-Gen Firewall Estates

Firewalls are an essential pillar of any enterprise network security strategy. They sift traffic coming in and going out of corporate networks, offering round-the-clock perimeter protection.

Even better are today’s next-generation firewalls (NGFWs), which bring interoperability and contextualization into the mix. These hybrid firewalls provide a more effective layer of protection as they combine both traditional firewalls with newer types.

Unfortunately, NGFWs and older versions for that matter are not the “be-all and end-all” of enterprise network security. They serve as a good starting point, but they also need to be appropriately configured to work — along with the right data feeds, which can include WHOIS history data, as this post will suggest.

Using a Domain History Checker: How to Avoid Gaining a Nasty Reputation from an Expired Domain

Have you ever thought of a domain name as one of the greatest business assets you could own? This may be the right time. A domain name serves a variety of purposes:

It’s an organization’s online distinct means of identification. It is what makes it stand out from the crowd, while usually containing the same or very similar terms as a business’s brand name. That is why it needs protection from abuse, such as copyright or trademark infringement.

How IP Lookup Geolocation Can Improve App Development

How IP Lookup Geolocation Can Improve App Development

App developers find it particularly challenging to make sense of user behavior. Often, users install apps out of curiosity and only use most of them once or twice before completely forgetting about them. Alternatively, they will uninstall these apps right after their curiosity is satisfied.

One way for app developers to increase user engagement and retention is by incorporating IP geolocation into their creations. By maximizing geolocation data, app developers can know their users better in a non-obtrusive manner as well as better figure out what stimulates retention.

DNS Records and Their History Matter: Beefing Up Your Cybersecurity Posture Using DNS Tools

The global cybersecurity landscape is becoming crowded both with threat actors and security solutions. When it comes to security threats specifically, attacks are becoming more and more sophisticated, and the amount of damage they cause is also increasing. In 2018, hackers stole almost half a billion personal records.

These security breaches were accomplished by using different tactics such as phishing, denial-of-service (DoS), and ransomware attacks, to name a few. And the threat actors successfully carried out these attacks, not because victims don’t use cybersecurity solutions, but because not all systems monitor every type of vulnerabilities — including the ones that have to do with DNS misconfigurations.

E-Commerce and Online Brands: How to Avoid and Tackle Trademark Infringement Issues with Brand Monitor

With all of the business growth opportunities that the Web provides for e-commerce sites and brands operating online in general, also come responsibilities and risks.

Customer privacy and data, for one thing, must be safeguarded against cyber attacks — notably phishing and spam campaigns that could lead to fraud and information and identity theft. Indeed, personally identifiable information (PII) such as Social Security and driver’s license numbers, health records, and payment card information, among others, are often stolen and sold in underground markets or used in attacks. A quick black market survey, for instance, revealed that health records and passport information are sold for as much as $1,000 per set in cybercriminal one-stop shops.

How to Fend Off DNS Attacks with DNS Reverse Lookup Tools

How to Fend Off DNS Attacks with DNS Reverse Lookup Tools

You might be aware of how much Domain Name System (DNS) attacks can cripple organizations and their online properties. The 2019 Global DNS Threat Report by IDC confirms this, stating that the average cost of a DNS attack has risen by 49% since last year to $1.27 million. Companies also reported that it takes their teams more than a day to fix breaches, thus drastically affecting operations and revenues.

Today, we’ll examine the worst DNS incidents to date and how a DNS reverse lookup tool like DNS Lookup API can help organizations build up domain intelligence against them.

From IANA to Using IP Netblocks WHOIS Database for IP Range Lookups

From IANA to Using IP Netblocks WHOIS Database for IP Range Lookups

More and more professionals rely on IP intelligence sources such as IP Netblocks WHOIS Database to learn more about IP addresses and their ranges (consecutively numbered sets of IP addresses). Many, however, do not have a full understanding of how IP netblocks and addresses are broken down in the first place and why this information can be useful.

Essentially, IP addresses are numbers from 0 to 536,870,911. Their distribution amongst users is done by Classless Inter-Domain Routing (CIDR). The idea is that the whole interval is split into parts assigned to different bodies responsible for them. These bodies will then split their IP address intervals into smaller ones and delegate their administration to other bodies or end-users. So finally the smallest intervals will have actual owners, or, vice versa, owners will have one or more intervals.
