SMS Shield feature

Your words. Your patterns. Your rules.

Filter texts by the keywords, patterns and repeat spam formats you choose. Set rules in a few clicks, and let MCM AI suggest new ones as fresh campaigns appear.

Rules you control

Three ways to say what gets through.

Start simple. Each list or rule is yours to add, edit and retire as your traffic changes, so your filtering always reflects what your network and your subscribers actually need.

01

Allow lists

Name the senders and phrases you always trust. Their texts go straight through, which also helps cut false positives.

02

Block lists

Name what you never want to carry. Matching texts are stopped before a subscriber sees them.

03

Keyword rules

Pick the words and phrases that give spam away. Each rule takes a few clicks to add, and you can edit it whenever you like.

Three outcomes

Every text ends up somewhere clear.

Once a message has been checked against your rules, one of three things happens to it.

Allowed

The text matches nothing you object to, or it comes from a sender on your allow list. It goes straight to the subscriber and nobody is slowed down.

Held for review

The text trips a softer rule, so it waits for a person. Your team can look it over and release anything genuine from the dashboard.

Blocked

The text matches a rule you have decided is never acceptable. It stops on your network and never reaches the subscriber.

Repeat spam formats

One pattern, every variation.

Spammers reuse the same message and swap the details: a name, a brand, an amount, a link. A pattern rule matches the shape instead of the exact words, so a single rule covers the whole family. That keeps your rule list short and easy to read, instead of growing with every small change a spammer makes.

MCM AI suggests

A shield that gets sharper every week.

You are not left writing every rule from scratch. MCM AI watches for new campaigns and brings you suggestions, and you keep the final say. Every suggestion is a starting point for your team, never a change made behind your back.

  1. 1

    A new campaign appears

    A fresh wave of spam starts reaching your network, in a format your rules have not seen yet.

  2. 2

    MCM AI spots the shape

    It notices the texts share wording or structure and groups them as one campaign.

  3. 3

    A rule is suggested

    MCM AI proposes a rule that would catch the campaign, ready for you to read.

  4. 4

    Your team decides

    A supervisor reviews the campaign in the dashboard and confirms the rule, or leaves it out.

FAQ

Keyword & pattern rules — frequently asked questions.

What are keyword and pattern rules?expand_more

They are filters you write yourself. A keyword rule matches words or phrases, and a pattern rule matches the shape of a message, so repeated spam formats are caught even when small details such as a name, brand or link change.

Do I need technical skills to create rules?expand_more

No. Allow lists, block lists and keyword rules are set up in a few clicks from the dashboard, so your support or operations team can manage them without waiting on engineers.

Can MCM AI help me write rules?expand_more

Yes. When a fresh spam campaign appears, MCM AI suggests a new rule for it. Your team reviews the campaign in the dashboard and decides whether to confirm the rule, so you stay in control while the shield gets sharper every week.

What if a good message is caught?expand_more

Any message can be released from the dashboard, and allow lists let you tune your rules to reduce false positives. Start with the senders and phrases you trust, then add stricter rules on top.

Do the rules work in other languages?expand_more

MCM AI reads message content in 30+ languages, so the campaigns it suggests rules for are not limited to one language.

Where does this sit in the platform?expand_more

It is part of SMS Shield, the messaging firewall in MCM Network Shield for operators and carriers, and it works alongside the other SMS Shield protections.
